BASIC WOODCHIPPING SAFETY
The operator should be aware of the following points:
MAINTAIN A SAFETY EXCLUSION ZONE around the chipper of at least 10 metres for the
general public or employees without adequate protection. Use hazard tape to identify this
working area and keep it clear from debris build up. Chips should be ejected away from any
area the general public have access to.
HAZARDOUS MATERIAL - Some species of trees and bushes are poisonous. The chipping
action can produce vapour, spray and dust that can irritate the skin. This may lead to
respiratory problems or even cause serious poisoning. Check the material to be chipped before
you start. Avoid confined spaces and use a facemask if necessary.
BE AWARE when the chipper is processing material that is an awkward shape. The material
can move from side to side in the funnel with great force. If the material extends beyond the
funnel, the brash may push you to one side causing danger. Badly twisted brash should be
trimmed before being chipped to avoid thrashing in the feed funnel.
BE AWARE that the chipper can eject chips out of the feed funnel with considerable force.
Always wear full head and face protection.
ALWAYS work on the side of the machine furthest from any local danger, e.g. not road side.
WARNING
The chipper will feed material through on its own. To do this, it relies on
sharp blades on the chipper rotor. To keep the blades sharp, only feed the
machine with clean brushwood. DO NOT put muddy/dirty wood, roots,
potted plants, bricks, stones or metal into the chipper. !
!
OPERATOR'S PERSONAL PROTECTIVE EQUIPMENT REQUIRED
Chainsaw safety helmet
fitted with mesh visor and
recommended ear defenders
to the appropriate
specifications.
Work gloves with
elasticated wrist.
Close fitting heavy-duty
non-snag clothing.

appropriate.
DO NOT
wear rings, bracelets,
watches, jewellery or any
other items that could be
caught in the material and
draw you into the chipper.
Steel toe cap safety boots.

DO’S AND DON’TS
GENERAL SAFETY MATTERS

speed.
ALWAYS check (visually) for fluid leaks.
ALWAYS take regular breaks. Wearing personal
protective equipment for long periods can be
tiring and hot.
ALWAYS keep hands, feet and clothing out of
feed opening, discharge and moving parts.
ALWAYS use the next piece of material or a push
stick to push in short pieces. Under no
circumstances should you reach into the funnel.
ALWAYS keep the operating area clear of people,
animals and children.
ALWAYS keep the operating area clear from
debris build up.
ALWAYS keep clear of the chip discharge tube.
Foreign objects may be ejected with great force.
ALWAYS ensure protective guarding is in place
before commencing work. Failure to do so may
result in personal injury or loss of life.
ALWAYS use chipper in a well ventilated area -
exhaust fumes are dangerous.

OPERATING INSTRUCTIONS 9
STARTING THE ENGINE
TURN the fuel valve to the ‘ON’ position.
MOVE the choke lever to the ‘CLOSE’ position. NOTE: Do not use the choke if the engine is
warm or the air temperature is high.
MOVE the throttle control lever slightly to the left.
TURN the engine switch to the ‘ON’ position.
PULL the starter grip lightly until resistance is felt, then pull briskly.
CAUTION: Do not allow the starter grip to snap back against the engine. Return it gently
to prevent damage to the starter.
AS the engine warms up, gradually move the choke lever to the ‘OPEN’ position.
POSITION the throttle control lever for the desired engine speed.
LOCATE the machine on firm level ground.
CHECK engine oil level.
CHECK the fuel valve is open.
CHECK all guards are in place.
CHECK the discharge unit is pointing in a safe direction.
CHECK the feed funnel to ensure no objects are inside.
For parts location see diagrams on pages 3 & 4.
STOPPING THE ENGINE
MOVE the throttle control lever fully to the right.
TURN the fuel valve to the ‘OFF’ position.
DAILY CHECKS BEFORE STARTING
STARTING TO CHIP
WARNING
Do not use or attempt to start the chipper without the protective
guarding and discharge unit securely in place. Failure to do so may
result in personal injury or loss of life.
!!
CHECK that the chipper is running smoothly.
STAND to one side of the feed funnel.
PROCEED to feed material into the feed funnel.
CHIPPING
Wood up to 75 mm in diameter can be fed into the feed funnel. Enter it into the funnel butt end first.
Release the material before it engages the rotor. Some pieces of wood may move around significantly
whilst being chipped.
The wood will be drawn into the cutting blade quite quickly, be ready for this to happen. Stand well
clear.
A piece of wood which is too tough or too large for the chipper will slow the engine down. When this
happens it is possible to hold back the branches that are being chipped and allow the engine to regain
its speed again.
If a piece of wood gets stuck in the funnel and it cannot be chipped due to its size or shape, it will need
to be removed. Trim the branch until it is a suitable shape for the chipper to accept.
