IMPORTANT SAFETY INSTRUCTIONS

When using your garage equipment, basic safety precautions should always be followed, including the
following:

1. Read all instructions.

2. Care must be taken as burns can occur from touching hot parts.

3. Do not operate equipment with a damaged cord or if the equipment has been dropped or damaged ­until it has been examined by a qualified serviceman.

3. Do not let cord or hoses come in contact with hot manifolds or moving fan blades.

4. If an extension cord is necessary, a cord with a current rating equal to or more than that of the
equipment should be used. Cords rated for less current than the equipment may overheat. Care
should be taken to arrange the cord so that it will not be tripped over or pulled.

5. Always unplug equipment from electrical outlet when not in use. Never use the cord to pull the
plug from the outlet. Grasp plug and pull to disconnect

6. To reduce the risk of fire, do not operate equipment in the vicinity of open containers of flammable
liquids (gasoline). WARNING: Risk of Explosion: This equipment has internal arcing and
sparking parts which should not be exposed to flammable vapors. This equipment is only suitable
for installation in a garage having sufficient air circulation to be considered a non-hazardous
location.

7. Adequate ventilation should be provided when working on operating internal combustion engines.

8. Keep hair, loose clothing, fingers, and all parts of body away from moving parts.

9. To reduce the risk of electric shock, do not use on wet surfaces or expose to rain.

10. Use only as described in this manual. Use only manufacturer’s recommended attachments.

11. ALWAYS WEAR SAFETY GLASSES. Everyday eyeglasses only have impact resistant lenses,
they are NOT safety glasses.

The Automotive Lift Institute (ALI) is a trade association comprised of US and Canadian manufacturers and
certain national distributors of automotive lifts. For almost 50 years, the ALI in cooperation with the
American National Standards Institute (ANSI) has continued to sponsor the national standard ANSI/ALI
ALCTV-1998 "Safety Requirements for Construction, Testing, and validation for Automotive Lifts.”

The new "ALI/ETL Automotive Lift Certification Program" is based on ALI developed methods and criteria
for third party testing of automotive lifts to validate conformance with ANSI/ALI ALCTV- 1998.

For automotive lifts to be certified, manufacturers must execute an agreement with the ALI and ETL / Intertek
Testing Services and must meet certain requirements:

♦ Must be structurally tested in accordance with the test requirements as outlined in ANSI/ALI ALCTV-

1998.

♦ All motor operated units must be listed by a nationally recognized testing laboratory (NRTL) in

accordance with ANSI/UL 73.

♦ The manufacturer's production facility must meet quality control requirements as set forth in the ANSI

Z34.1-1987 and the ALI/ETL Automotive Lift Certification Program Procedural Guide.

♦ All manufacturer-provided instructions, manuals, and operator safety documents, must meet the

requirements of the ANSI/ALI ALCTV–1998 and ANSI/UL73.

Lifts meeting these rigid requirements may be listed in the directory of certified lifts and be labeled with the
"ALI/ETL certification mark" (Above on right), and, if applicable, the ETL listing mark to ANSI/UL-73.

Mohawk has been a long-standing member of ALI and most of Mohawk’s popular models are currently listed
and certified. Other Mohawk models are in various stages of testing. To obtain a complete and current
certification listing, contact Mohawk Resources Ltd. To obtain a copy of the current automotive lift standard,
contact ALI or ANSI.

Some people purchase quality products and others do not. You are assured of quality when you purchase a
Mohawk product in compliance with the certification program.

BEFORE INSTALLING A LIFT

IMPORTANT

BEFORE INSTALLING A MOHAWK LIFT THERE ARE A FEW ITEMS THAT MUST BE INSPECTED. EACH REPAIR SHOP BAY IS DIFFERENT. IN
AN ATTEMPT TO PREVENT OVERSIGHTS, ALL OF THE FOLLOWING INFORMATION IS TO BE VERIFIED.

OVERHEAD OBSTRUCTIONS

THE AREA WHERE THE LIFT WILL BE LOCATED SHALL BE FREE
OF OBSTRUCTIONS. HEATERS, BUILDING SUPPORTS,
ELECTRICAL CONDUIT; ALL OF THESE ITEMS ARE TO BE
TWELVE FEET ABOVE THE BAY FLOOR. SEE FIGURE 1 & 8.

DEFECTIVE CONCRETE

VISUALLY INSPECT THE BAY FLOOR AREA. THE UNIT CANNOT
BE INSTALLED ON EXPANSION SEAMS, OR CONCRETE THAT IS
CRACKED. THE UNIT IS ONLY AS STRONG AS THE FLOOR IT IS
INSTALLED ON.

FLOOR REQUIREMENTS

THIS INFORMATION IS IN THE GENERAL FLOOR REQUIREMENTS.
IF THE BAY FLOOR DOES NOT CONFORM TO THESE
SPECIFICATIONS, REFER TO THE “NEW SLAB
RECOMMENDATIONS” SECTION IN THIS MANUAL.

LOCATE THE MAIN SIDE POST ON THE HIGH SIDE OF THE FLOOR
IF A SLOPE IS NOTED. REFER TO FIGURE 9.

POWER SUPPLY

THE STANDARD POWER UNIT IS 220-VOLT SINGLE PHASE. REFER
TO THE POWER UNIT SPECIFICATIONS SECTION. REQUIREMENTS
MAY VARY ON SPECIAL ORDERS.

THE MAIN SIDE POST WILL REQUIRE THE POWER SUPPLY FOR
THE UNIT. NOTE THE LOCATION OF THE POWER SUPPLY.

BAY SIZE

TO OPTIMIZE SHOP SPACE, IT IS ADVISED TO LOCATE A VEHICLE
IN THE BAY PRIOR TO LAYOUT. NOTE WALKWAY’S OVERHEAD
OBSTRUCTIONS, AND ABILITY TO MOVE EQUIPMENT IN THE
BAY AREA. REFER TO FIGURE 1 & 8.

REQUIREMENTS MAY VARY ON SPECIAL ORDERS.

SPECIFICATIONS

REFERENCE ALL SPECIFICATIONS PRIOR TO INSTALLING A LIFT.

WARNING

BEFORE DRILLING THE MOUNTING HOLES
