CEILING HEIGHT WARNING
WARNING:
Ensure that ceiling height* and/or overhead hydraulic line height is greater than the total
lifted height of the tallest vehicle (maximum vehicle height plus lift stroke). Failure to
ensure adequate overhead clearance may cause damage to equipment, vehicle and bodily
injury to the user.
NOTICE:
In the event that the ceiling height* or hydraulic line height is reduced less than the
standard heights recommended for the lift, an OVERHEAD SHUT-OFF DEVICE
MUST BE EMPLOYED.
Note that underground hydraulic lines are available, but the ceiling height* must still be
adequate to provide clearance for the tallest lifted vehicle. Ensure that the whole fleet of
vehicles is reviewed and the tallest vehicle used.
*Overhead obstruction of any kind must be taken into account (i.e. overhead heaters,
garage doors, beams, etc..)

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:2011 "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:2011.
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:2011.
All motor operated units must be listed by a nationally recognized testing laboratory (NRTL) in
accordance with ANSI/UL-201.
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:2011 and ANSI/UL-201.
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-201.
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. or visit www.mohawklifts.com or www.ali-
directory.org To obtain a copy of the current automotive lift standard, contact ALI or ANSI or visit
www.autolift.org
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.

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. REFER TO
FIGURE 1.
LOCATE THE MAIN SIDE POST ON THE HIGH SIDE OF THE FLOOR
IF A SLOPE IS NOTED. REFER TO FIGURE 11.
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 2 & 10.
REQUIREMENTS MAY VARY ON SPECIAL ORDERS.
SPECIFICATIONS

2-POST LIMITATIONS AND ADAPTER
USAGE:
REV (2/9/2006)
2-POST LIMITATIONS:
ALL MOHAWK 2-POST LIFTS ARE FOR INDOOR USE UNLESS
SPECIFICALLY QUALIFIED AND MODIFIED FOR A CUSTOM
ENVIRONMENT.
ALL MOHAWK 2-POST LIFTS MUST ACCOMPLISH THREE MAIN
CRITERIA IN ORDER TO LIFT A VEHICLE SAFELY:
1. PROPER FRAME ENGAGEMENT WITH PADS. ALL 2-
POST FRAME ENGAGING LIFTS ARE DESIGNED TO LIFT
STANDARD VEHICLES WITHIN THEIR RATED
CAPACITY BY THE VEHICLE FRAME. IF SUITABLE
FRAME CONTACT LIFT POINTS CAN NOT BE REACHED
OR ACCOMMODATED BY THE LIFTING PADS, THE
VEHICLE MUST NOT BE RAISED WITH THE LIFT. REFER
TO VEHICLE MANUFACTURER LIFTING POINT
SPECIFICATIONS (AND VEHICLE LIFT POINT LABEL PER
SAE J2184, VEHICLE LIFT POINTS FOR SERVICE
GARAGE LIFTING).
2. PROPER CENTER OF GRAVITY PLACEMENT OF
VEHICLE ON LIFT ENSURE THAT THE CENTER OF
GRAVITY OF THE VEHICLE LIES CENTERED BETWEEN
THE LIFTING ARMS. THIS SHOULD PLACE THE CENTER
OF GRAVITY OF THE VEHICLE IN LINE WITH THE
CENTER OF THE POSTS AS WELL.
3. PROPER LOADING OF ARMS. INDIVIDUAL ARM
CAPACITIES ARE ¼ OF THE RATED LIFT CAPACITY,
AND MUST NOT BE EXCEEDED. FOR INSTANCE, A 10,000
LB RATED 2-POST LIFT HAS ARMS THAT ARE RATED
FOR 2,500 LBS EACH. IT IS POSSIBLE THAT A 10,000 LB
VEHICLE CAN OVERLOAD THE ARMS ON A 10,000 LB
LIFT IF THE FRONT AND REAR LOADING ARE NOT
EQUAL.
WITH RESPECT TO HEAVY ENDED VEHICLES SUCH AS FORK
TRUCKS, DELIVERY VANS, PICKUP TRUCKS, ETC, ATTENTION
MUST BE MADE TO ENSURE THAT THE PER ARM CAPACITY OF
THE LIFTING ARMS IS NOT EXCEEDED AND THAT THE CENTER
OF GRAVITY OF THE VEHICLE LIES CENTERED BETWEEN THE
LIFTING ARMS.
SPECIAL SAFETY PRECAUTIONS MUST BE OBSERVED IN
APPLICATIONS INVOLVING VERY LONG AND VERY SHORT
WHEELBASE VEHICLES. 2-POST LIFTS ARE NOT DESIGNED TO
RAISE STRETCHED LIMOS AND OTHER TYPES OF LONG WHEEL
BASE VEHICLES. AS A RULE OF THUMB, THE VEHICLE LENGTH
ON A 2-POST MUST BE LIMITED TO 4 TIMES THE LENGTH OF THE
ARM SPREAD TO RAISE IT. THE CENTER OF GRAVITY ON THIS
VEHICLE MUST LIE BETWEEN THE LIFTING PADS TO
ACCOMPLISH THIS. NOTE THAT SOME VEHICLES, PER VEHICLE
MANUFACTURER GUIDELINES, ARE NOT TO BE RAISED BY THE
FRAME. REFER TO VEHICLE MANUFACTURER GUIDELINES FOR
PROPER LIFTING TECHNIQUES.
THIS LIFT IS NOT INTENDED, NOR DESIGNED, TO LIFT VEHICLE
FRONT OR BACK ENDS USING ONLY TWO ARMS.
CARE MUST BE OBSERVED WHEN REMOVING ANY HEAVY
COMPONENTS FROM A VEHICLE AND THEREBY DRASTICALLY
SHIFTING THE VEHICLE CENTER OF GRAVITY (I.E. ENGINE
REMOVAL, TRANSMISSION REMOVAL, ETC.). THE USE OF JACK
STANDS AT THE FRONT AND REAR ENDS OF THE VEHICLE IS
HIGHLY RECOMMENDED WHEN PERFORMING THIS TYPE OF
WORK.
ADAPTER USAGE AND LIMITATIONS:
THE USE OF HEIGHT ADAPTERS IS COMMON FOR MOST LIFTING
SITUATIONS TO ACCOMMODATE HIGH FRAMES AND LOW
OVERHANGING BODIES OF VEHICLES.
FOR A-7, A-7A, SYSTEM IA, SYSTEM IA-10, TOMAHAWK-9000:
THESE LIFTS COME STANDARD WITH (4) 3” AND (4) 6” HEIGHT
ADAPTERS.
THESE LIFTS ARE ONLY ALLOWED TO USE 2 ADAPTERS WHEN
STACKED: ONE (1) 6” AND ONE (1) 3” ADAPTER, RESULTING IN 9”
MAXIMUM STACKING HEIGHT. LONGER CUSTOM SINGLE PIECE
ADAPTERS ARE AVAILABLE UPON REQUEST.
FOR LMF-12, TP-15, TP-16, TP-18, TP-20, TP-26, TP-30:
THESE LIFTS COME STANDARD WITH (4) 5”, (4) 7 ½”, AND (4) 10”
HEIGHT ADAPTERS.
THESE LIFTS ARE ONLY ALLOWED TO USE 2 ADAPTERS WHEN
STACKED: ONE (1) 10” AND ONE (1) 7½” ADAPTER, RESULTING IN
17 1/2” MAXIMUM STACKING HEIGHT. LONGER CUSTOM SINGLE
PIECE ADAPTERS ARE AVAILABLE UPON REQUEST.
THE USER SHOULD BE WARNED THAT ANY SITUATION
PRODUCING AN OFF-VERTICAL SLANTING OF THE HEIGHT
ADAPTERS, SUCH AS DEFLECTION OF THE ARM DUE TO HEAVY
LOAD, DEFLECTION OF THE ARM DUE TO SLOP, ECCENTRIC
CORNER LOADING OF THE LIFT PAD, ETC. MUST BE AVOIDED.
CUPPED OR YOKE STYLE LIFTING PADS (WHICH DO NOT RELY
ON FRICTION) ARE ALSO AVAILABLE FOR SITUATIONS
INVOLVING LIFTING NON-FLAT SURFACES. CONSULT MOHAWK
SERVICE DEPARTMENT FOR CUSTOM PAD REQUESTS FOR YOU
APPLICATION.
