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 IN WHICH THE LIFT WILL BE LOCATED SHALL BE FREE
OF OBSTRUCTIONS. HEATERS, BUILDING SUPPORTS, ELECTRICAL
CONDUIT; ALL OF THESE ITEMS ARE TO BE NINETEEN FEET
MINIMUM ABOVE THE BAY FLOOR. SEE FIGURE 3.

DEFECTIVE CONCRETE

VISUALLY INSPECT THE BAY FLOOR AREA. THE UNIT CAN NOT BE
INSTALLED ON EXPANSION SEAMS, OR CONCRETE WHICH 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 THE BACK OF THIS MANUAL.

ALWAYS USE SHIM PLATES TO LEVEL POST INSPECT BAY FOR
EXCESSIVE SLOPE AND DETERMINE WHAT IS NEEDED FOR
SHIMMING BEFORE INSTALLING LIFT. SEE FIGURE 2.

POWER SUPPLY

THE STANDARD POWER UNIT IS 220 VOLT SINGLE PHASE. REFER
TO THE LIFT VERIFICATION SHEET FOR SPECIFICATIONS ON
SPECIAL ORDERS.

THE POWER SUPPLY SHOULD BE AVAILABLE PRIOR TO
INSTALLATION. IT IS ADVISED TO HAVE A LICENSED ELECTRICIAN
PERFORM ALL ELECTRICAL.

BAY SIZE

NOTE WALKWAYS, OVERHEAD OBSTRUCTIONS, AND ABILITY TO
MOVE EQUIPMENT IN THE BAY AREA.

REFER TO THE LIFT SPECIFICATIONS. REFER TO THE LIFT
VERIFICATION SHEET FOR SPECIFICATIONS ON SPECIAL ORDERS.

SPECIFICATIONS

REFERENCE ALL SPECIFICATIONS PRIOR TO INSTALLING A LIFT.

WARNING

BEFORE DRILLING THE MOUNTING HOLES

• REFERENCE ALL FIGURES PERTAINING TO DRILLING, WEJ-IT

WARNINGS, AND INSTALLATION INSTRUCTIONS

• ALWAYS VERIFY SQUARE AND LEVEL STRUCTURE BEFORE

DRILLING.

• USE A SHARP DRILL BIT TO PREVENT DRILLING AN UNDERSIZED

HOLE. DRILL THE HOLE EQUAL TO THE LENGTH OF THE WEJ-IT
ANCHOR. BLOW OUT THE HOLE WITH SHOP AIR, OR VACUUM.
INSERT THE WEJ-IT ANCHOR SO THAT THE WASHER RESTS
AGAINST THE POST FOOTING. TIGHTEN THE NUT 3 TO 5 FULL
TURNS PAST HAND TIGHT. ( 175 FOOT POUNDS )

12

• NEVER USE AN IMPACT TOOL TO TIGHTEN THE WEJ-IT

ANCHORS. USE A TORQUE WRENCH ONLY.

• MAKE SURE THE CONCRETE IS SOLID WHEN DRILLING. CRACKS

AND EXPANSION SEAMS REDUCE THE EFFECTIVENESS OF THE
