engineering department must be made aware in advance of these conditions and any additional code requirements that
must bemet.
Also, the foundation for which this lift must be installed on must comply to the minimum specifications as set forth in
this manual. Any drainage slopes in the bay where the lift is to be installed must be directed away from the posts to
prevent water accumulation at the post bases.
Standard foundation flooring and anchorage specifications are contained within this manual. For installation within a
seismic area, a qualified person must be consulted to address seismic loads and other local or state requirements.

All accessories (i.e. jacking beams, etc.) supplied with this lift are to be used on this lift only. Accessories
from other lifts are not acceptable and could result in injury to the user.
If attachments, accessories or configuration modifying components are used on this lift and, if they are not
certified for use on this lift, then the certification of this lift shall become null and void. Contact the
participant (.) for information pertaining to certified attachments, accessories or
configuration modifying components.

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 . 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.

4-POST LIMITATIONS:
REV (4/4/2011)
4-POST LIMITATIONS:
ALL MOHAWK 4-POST LIFTS ARE FOR INDOOR USE UNLESS SPECIFICALLY QUALIFIED AND
MODIFIED FOR A CUSTOM ENVIRONMENT.
ALL MOHAWK 4-POST LIFTS MUST ACCOMPLISH THREE MAIN CRITERIA IN ORDER TO LIFT
A VEHICLE SAFELY:
1. PROPER CAPACITY. ALL 4-POST RUNWAY LIFTS ARE DESIGNED TO LIFT STANDARD
VEHICLES WITHIN THEIR RATED CAPACITY WITHIN THE CAPACITY OF THE LIFT
RATING. ANY VEHICLES EXCEEDING THE CAPACITY MUST NOT BE RAISED.
2. PROPER CENTER OF GRAVITY PLACEMENT OF VEHICLE ON LIFT ENSURE THAT
THE CENTER OF GRAVITY OF THE VEHICLE LIES CENTERED ALONG THE LENGTH OF
THE TRACKS. WITH RESPECT TO HEAVY ENDED VEHICLES SUCH AS FORK TRUCKS,
DELIVERY VANS, PICKUP TRUCKS, ETC, THE VEHICLE MAY NEED TO BE POSITIONED
FORWARD OR REARWARD TO CENTER THE LOAD ON THE TRACKS. ALSO, THE
VEHICLE SHOULD BE CENTERED SIDE TO SIDE ON THE LIFT TRACKS AS WELL.
3. PROPER CHOCKING OF TIRES. USE CHOCKS SUPPLIED, AND CHOCK TIRES ON
BOTH TRACKS.
SPECIAL SAFETY PRECAUTIONS MUST BE OBSERVED IN APPLICATIONS INVOLVING VERY
LONG AND VERY SHORT WHEELBASE VEHICLES. THE WHEEL BASE RANGE ON VERY LONG
VEHICLE MAY NOT ALLOW FOR PROPER POSITIONING OF TIRES ON TRACKS TO GET THE
CENTER OF GRAVITY OF THE VEHICLES CENTERED WITH THE CENTER OF THE TRACK
LENGTH. SHORT WHEEL BASE VEHICLES MAY OVERLOAD THE CENTRAL LENGTH OF THE
TRACKS. AS A RULE OF THUMB, ALL MOHAWK 4-POST RUNWAY LIFTS ARE DESIGNED TO
ACCOMMODATE WHEEL BASES THAT ARE ~3 FEET SHORTER THAN THE LENGTH OF THE
TRACKS (MORE IF VEHICLES ARE FAIRLY EVENLY LOADED FRONT TO REAR) AND WHEEL
BASES AS SHORT AS 10 FEET (LESS IF VEHICLES ARE LIGHTER). REFER TO VEHICLE
MANUFACTURER GUIDELINES FOR PROPER LIFTING TECHNIQUES.
PRIOR TO LIFTING LOW PROFILE VEHICLES, RAMPS SHOULD BE CHECKED TO ENSURE
PROPER CLEARANCE FOR ENTRY AND BREAK OVER OF THE VEHICLE UNDERCARRIAGE.
(IE. STRETCHED LIMOS.). LONGER RAMPS MAY BE REQUIRED.
THIS LIFT IS NOT INTENDED, NOR DESIGNED, TO LIFT VEHICLE BY ONLY THE FRONT OR
ONLY THE BACK ENDS.
THIS LIFT IS NOT INTENDED TO BE DRIVEN ON TO OR OFF OF, UNLESS WHEN IT IS FULLY
LOWERED.
(THIS IS NOT AN ELEVATOR LIFT).
THIS LIFT IS NOT INTENDED FOR THE LIFTING OF PEOPLE.
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.
