SAFETY RULES
- Do not allow unauthorized personnel to operate serv-
ice or maintain this machine.
- Do not wear rings, wrist watches, jewellery, loose or
hanging apparels, such as ties, torn clothing, scarves,
unbuttoned or unzipped jackets that can catch on mov-
ing parts. Wear proper safety equipment as recom-
mended for the job. Examples: hard hat, heavy gloves,
ear protection, safety glasses or goggles, reflector vests,
respirator. Consult your employer for specific safety
equipment requirements.
- Keep operator's compartment, stepping points, grab rails
and handles clear of foreign objects, oil, grease, mud
or snow accumulation to minimize the danger of slip-
ping or stumbling. Clean mud or grease from shoes
before attempting to mount or operate the machine.
- Do not jump on or off the machine. Keep two hands
and one foot, or two feet and one hand in contact with
step grab rails and handles at all times.
- Do not use controls or hoses as hand holds when climb-
ing on or off machine. Hoses and controls are movable
and do not provide a solid support. Also, controls may
be inadvertently moved causing accidental machine or
equipment movement.
- Never attempt to operate the machine or its tools from
any position other than seated in the operator's seat.
- Keep head, body, limbs, hands and feet inside opera-
tor's compartment at all times, to reduce exposure to
hazards outside the operator's compartment.
- Be careful of slippery conditions on stepping points,
hand rails, and on the ground. Wear safety boots or
shoes that have a high slip resistant sole material.
- Do not leave the machine until it is completely stopped.
- Check the seat safety belt at least twice a year. If there
are signs of wear or fraying or other signs of weakness
that could lead to failure, replace it.
STARTING
- NEVER START NOR OPERATE AN UNSAFE MA-
CHINE. Before operating a machine, always ensure that
any unsafe condition has been satisfactorily remedied.
- Check brakes, steering and attachment controls before
moving. Advise the proper maintenance authority of any
malfunctioning part or system.
- Be sure all protective guards or panels are in place,
and all safety devices provided are in place and in good
operating conditions.
- Be sure exposed personnel in the area of operation are
clear of the machine before moving it or its attachments.
WALK COMPLETELY AROUND the machine before
mounting. Sound horn.
- Before starting machine, check, adjust and lock the
operator's seat for maximum comfort and control of the
machine.
- Fasten your seat belt (when provided).
- Obey all flag signals and signs.
- Due to the presence on the machine of flammable flu-
ids, never check or fill fuel reservoirs or batteries near
open flames, smoking materials or sparks.
- REMEMBER THAT STARTING FLUID IS FLAMMABLE.
Follow strictly the recommendations printed on contain-
ers and in the Operation and Maintenance Manual.

SAFETY RULES
during operations. in case the brake pressure gauge
shows a pressure lower than the minimum operating
pressure, stop immediately the machine .
- DO NOT CARRY RIDERS ON MACHINE
- Study and familiarize with escape routes alternate to
normal exit routes.
- Seat belts are required by current regulations to be pro-
vided with Roll Over Protection Structures or cabs. Keep
safety belts fastened around you during operation.
- For your personal protection, do not climb on or off
machine while machine is in motion.
- Make sure that exposed persons in the area of opera-
tion are clear of the machine, before starting the engine
and operating the equipment. Sound horn. Obey all in-
dications provided by flags and signals.
- NEVER COAST the machine down grades and slopes
with the transmission in neutral or neutralized.
Choose and shift into the most appropriate gear to keep
the speed required, thus preventing any loss of control.
- Do not operate machinery in a condition of extreme
fatigue or illness. Be especially careful towards the end
of working shift.
- Do not operate machine with brakes out of adjustment.
- Operate the machine at speeds slow enough to ensure
complete control at all times.
- Travel slowly over rough terrain, on slopes or near drop-
offs, in congested areas or on ice or slippery surfaces.
- When backing, always look to where the machine is to
be moved. Be alert to the position of exposed person-
nel. DO NOT OPERATE if exposed personnel enter the
immediate work area. STOP THE MACHINE.
- Maintain a safe distance from other machines. Provide
sufficient clearance for ground and visibility conditions.
Yield right-of-way to loaded machines.
- Maintain clear vision of areas of travel or work. Keep
cab windows clean and repaired.
- When machines are operating in tandem, the pusher
(rear) must be equipped with the appropriate deflectors
to protect the unit in front from the air stream coming
from the radiator.
- When pulling or towing through a cable or chain, do not
start suddenly at full throttle; take-up slack carefully.
Inspect carefully for flaws or troubles before using.
- Avoid kinking cables. Do not pull through a kinked ca-
ble to the high stresses and possibility of failure of the
kinked area. Always wear heavy gloves when handling
cables.
- Be sure cables are anchored and the anchor points are
strong enough to handle the expected load. Keep ex-
posed personnel clear of anchor points and cables.
- DO NOT PULL UNLESS OPERATOR's COMPART-
MENT OF MACHINES INVOLVED ARE PROPERLY
GUARDED AGAINST POTENTIAL CABLE BACKLASH.
- Be alert to soft ground conditions close to newly con-
structed walls. The fill material and weight of the ma-
chine may cause the wall collapse under the machine.
- In darkness, check area of operation carefully before
moving in with machine. Use all lights provided. Do not
move into area of restricted visibility.
- If engine has a tendency to stall for any reason under
load or idle, report this for adjustment to proper mainte-
nance authority immediately. Do not continue to oper-
ate machine, until condition has been corrected.
- On machines supplied with suction radiator fans, be
sure to periodically check engine exhaust parts for leaks,
as exhaust fumes are dangerous to the operator.
- In case of closed type cabs, always keep an opening
with the outside, to ensure a constant air circulation.
- Operators must know thoroughly the performances of
the machine they are operating. When working on
slopes or near sudden level drops of the terrain, avoid
areas where ground is loose or soft since rolling-over
or loss of control of machine could result.
- Where noise exposure exceeds 90 dBA for 8 hours,
wear approved ear protection.
- When counterweights are provided, do not work ma-
chine if they have been removed.
- Overtaking maneuvers must be performed only when
absolutely necessary and unavoidable. Beware of pos-
sible uneven terrains, poor visibility conditions, the pres-
ence of other machinery or persons out of sight.
- Operate the machine at a speed adequate to the work-
ing conditions in the site and slow enough to ensure
complete control at all times.
- Never use the machine as a work platform or scaffold-
ing, nor other inappropriate operations (i.e. pushing
railway cars, trucks or other machines).
- Be alert of people in the operating area of the machine.
- When operating a machine, know in advance what clear-
ances will be encountered, overhead doors, cables,
pipes, bearing load limitations of ground, bridges, floors
or ramps.

SAFETY RULES
- When roading, find-out what conditions are likely to be
encountered, clearances, traffic congestion, type of road
surfacing, etc. Beware of fog, smoke or dust elements
that obscure visibility.
- When crossing gullies or ditches, move at an angle
with reduced speed after ensuring ground conditions
will permit a safe traverse.
- Explore the working area to identify potential risks such
as: slopes, overhangs, pits, demolition rubble, fires, ra-
vines, ditches, soft terrain, heavy traffic, crowded park-
ing areas, closed ambients. In such conditions, proceed
with extreme care.
- Whenever possible, avoid going over obstacles such
as rough terrain, rocks, logs highly irregular ground,
steps, ditches, railroad tracks. When obstructions must
be crossed, do so with extreme care at an angle, if pos-
sible. Reduce speed, shift-down. Ease up to the break
over point, pass the balance point slowly on the ob-
struction and ease down on the other side.
- In steep down-hill operation, do not allow engine to
over-speed. Select proper gear before starting down
grade.
- Avoid side hill travel, whenever possible. Drive up and
down the slope. Should the machine slipping sideways,
turn it immediately downhill.
- The grade of slope you should attempt will be limited by
factors such as condition of the ground, load being han-
dled, type of machine, speed of machine and visibility.
- There is no substitute for good judgment when working
on slopes.
- Avoid operating equipment too close to an overhang or
high wall, either above or below the machine. Be on the
look-out for caving edges, falling objects and slides.
Beware of concealment by brush and undergrowth of
these danger.
- When pushing-over trees, the machine must be
equipped with proper overhead guarding. Never allow
a machine to climb up on the root structure particularly
while the tree is being felled. Use extreme care when
pushing over any tree with dead branches.
- When pushing trees with dead limbs, proceed with ex-
treme care. Avoid brush piles, logs or rocks.
- NEVER DRIVE OVER THEM or other surface irregulari-
ties that brake traction with the ground, especially when
on slopes or near drop-offs.
- Be alert to avoid changes in traction conditions that
could cause loss of control. DO NOT DRIVE on ice or
frozen ground conditions when working the machine
on steep slopes or near drop-offs.
- Working in virgin and rough terrains is characterized by
the presence of all the perils and risks listed above. In
these conditions, it is emphasized the danger repre-
sented by large tree limbs (possibly falling on the ma-
chine), large roots (acting as a leverage under the ma-
chine when up-rooted causing the roll-over of the unit)
etc..
STOPPING
- When the machine is stopped for whatever reason, fol-
low the instructions of sections "Stopping the machine"
and "Stopping the engine" of the Operation and Main-
tenance Instruction Manual.
- Always remember to position the transmission drive
control in neutral and engage the control lock to secure
the machine.
- The parking brake is automatically set, when the trans-
mission safety lever is lowered.
- NEVER LEAVE THE MACHINE UNATTENDED with the
engine running.
- Always, before leaving the operator's seat and after
making sure all people are clear of the machine, slowly
lower the attachments or tools flat to the ground in a
positive ground support position.
- Return the controls to rest position. Place the gearshift
lever in neutral. Disconnect the master switch and ex-
tract the key.
- Park in a non- operating and no-traffic area or as in-
structed. Park on firm level ground if possible. Where
not possible, position machine at a right angle to the
slope, making sure there is no danger of uncontrolled
sliding movements.
- If parking in traffic lanes cannot be avoided, provide
appropriate flags, barriers, flares and signals as re-
quired. Also provide advance warning signals in the
traffic lane of approaching traffic.
- Keep head, body, limbs, feet, fingers or hands away
from bucket, blade or ripper when in raised position.
- Always disconnect the master switch before any inter-
vention (i.e. cleaning, repairing, maintaining, refueling
etc.). Do the same when parking for prolonged periods
of time to avoid accidental or unauthorized starting.
- Never lower attachments or tools other than seated in
