16. Do not allow snow to accumulate on the Car Shelter as the canopy could

collapse. The Car Shelter could topple in strong winds, causing damage to

personal property. Disassemble if weather conditions become severe and could

damage the Car Shelter. Clear heavy debris off the shelter before going under

it. Harbor Freight Tools is not responsible for damage due to weather conditions

and will not be held responsible for a Car Shelter exposed to and/or damaged by

conditions such as high winds, heavy rain, snow or ice under any conditions.

17. Do not attempt to move an assembled Car Shelter.

18. Do not sit or stand on top of the Car Shelter, and do not place anything on

top of the Car Shelter.

19. Snow/debris accumulation hazard. The heavy weight of accumualted snow or

other debris can cause parts of this Car Shelter to buckles suddenly. Do not allow

debris to accumualte on top of the Car Shelter. If snowfall is expected, place

additional supports (not provided) underneath the roof. NEVER enter a Car

Shelter with accumulated debris on top.

20. WARNING! Ladders are inherently dangerous equipment to use. If you are

using a ladder to assemble this product, make sure to read and adhere to the

safety warnings and instructions as recommended by the manufacturer/

distributor of the ladder you are using.

21. Prolonged exposure to wind can cause fasteners and hardware to loosen

as the frame exes. The Car Shelter’s frame strength will be compromised if

fasteners and hardware are not tight. Periodically, check to make sure all

fasteners and hardware are tight. Tubes and Anchors should also be periodically

checked to make sure the unit is always structurally rigid.

22. WARNING! Do not allow the vehicle’s engine to run while parked

within the Car Shelter. When running, the engine of a vehicle produces carbon

monoxide, a colorless, odorless, toxic gas that, when inhaled, can cause serious

personal injury or death.

23. WARNING! The warnings and cautions discussed in this manual

cannot cover all possible conditions and situations that may occur. It must be

understood by the operator that common sense and caution are factors which

cannot be built into this product, but must be supplied by the operator.

FOUNDATION

Prior to assembly, a proper foundation must be laid. The Car Shelter must be

properly supported to help prevent property damage and injury in the event

of strong winds or inclement weather. Wind and ground conditions may vary

from site to site, and may affect the practicality and effectiveness of anchoring

methods substantually. If you have any doubt regarding the stability of the

foundation you are to use, consult a professional.

It is always your responsibility to ensure that the Car Shelter is properly

anchored. Harbor Freight Tools cannot be held responsible for personal injury,

damage to the Car Shelter, or other property damage that occurs as a result of

improperly anchoring the Car Shelter.

Be certain to check with local authorities to obtain all required building permits

and to famialrize yourself with any building codes that may apply.

Decide on a location for the Car Shelter. The location should optimally be a

level, well-lit area that is sheltered from the wind. The entrance of the Car Shelter

should not open towards the prevailing wind, if possible.

IMPORTANT - READ THE FOLLOWING CAREFULLY BEFORE PROCEEDING

Site Preparation For Concret Foundation

1. It is recommended the Car Shelter be placed on a concrete foundation that is

level side to side and sloped about 1/8” per foot from front to back or back to

front to allow for proper drainage. DO NOT USE THE ANCHOR STAKES (7) TO

SECURE THE CAR SHELTER TO A CONCRETE BASE.

2. If you will be pouring a concrete slab for your Car Shelter, the slab should be at

least 5” thick and the concrete 2,500 to 3,000 PSI. NOTE: Make sure the slab

is completely dry before installation.

3. The outside dimensions of the concrete slab should be at least 3” larger than the

outside frame dimensions of the Car Shelter. Example: If the outside frame

dimensions of the Car Shelter is 18’1/4” long and 12’3-7/8” wide the concrete

slab dimensions should be 18’3-1/4” long and 12’6-7/8” wide. This will allow

the Anchor Bolts (10) to be 3” from the edge of the slab. (See Figure A.)

Assembling And Positioning The End Base And Center Base Rails:

1. Lay out the four End Base Rails (5) and two Center Base Rails (6) on the

concrete slab. (See Figure B, next page.)

Ground Installation (“Caisson”)

1. When installing the Car Shelter to the ground, dig a post hole 12” in diameter and

24” deep. Dig ten holes of similar depths, using the four End Base Rails (5) and

two Center Base Rails (6) as guides for where the holes should be dug.

2. Use a post hole digger or auger (not included) to drill your 30” deep holes into the

 ground.Cleanouttheholes.LayoutthebaserailsandttheAnchorStakes(7)

3. You should wait at least seven days for the concrete to properly set in the holes

before continuing with the Car Shelter assembly.

SKU 94939 For technical questions, please call 1-800-444-3353 PAGE 7

2. Join the End Bases (5) and Center Bases (6) together.

(See Figure B.)

3. Using a tape measure (not included), take a measurement across the diagonals

of the frame to check it for squareness. Adjust the frame until the measurments

are equal. (See Figure B.)

4. After you have completed all measurements and have the End Base (5) and

Center Base (6) Rails in place and squared, screw the joints together with two

Self Tapping Screws (8) per joint on the top surface of the Base Rails.

(See Figure B.)

Anchoring The End Bases And Center Bases To The Concrete Slab:

1. To drill the anchor holes, you will need a hammer drill and a 1/2” diameter

concrete drill bit (neither included).

2. Hold the Base Rails (5, 6) in place with your foot. Insert the 1/2” diameter

concrete drill bit through the anchor holes in the Base Rails and drill the holes

about 5” deep into the concrete slab. (See Figure C.)

3. Once the holes are drilled, use an air compresser to blow out the concrete dust

with compressed air from each of the holes. WARNING: To avoid inhaling dust

particles, wear a protective mask or face shield. (See Figure C.)

4. Use a hammer to tap the cement anchors (not included) through the pre-drilled

holes into the concrete slab surface. Continue tapping the cement anchors until

their washers rest against the top edge of the Base Rails (5, 6). (See Figure C.)

5. Firmly tighten the nuts of the cement ancors (not included) to secure the Base

Rails (5, 6) to the concrete slab surface. (See Figure C.)

6. When securing to the ground, use the Anchor Stakes (7) in place of the

cement anchors. Please Note: Before set up, be sure that the ground where

the Stakes are installed is free of any underground pipes or wires.

Roof And Wall Assembly:

1. Before assembling the roof and wall sections, stack the Peak Tubes (2). Line up

their ends and mark a line on the top of each Peak Tube 17-1/8” from one end.
