ANCHORING TIPS
1. Anchor must be at least 5” from the edge of the slab or any seam.
2. Use a concrete hammer drill with a 3/4” carbide bit.
3. Do not use a worn bit.
4. Drill in a perpendicular line with the hole.
5. Do not apply excessive pressure to the drill. Let the drill do the work.
6. Lift the drill up and down occasionally to remove residue and to reduce binding.
7. Drill the hole depth equal to the length of the anchor, or completely through the slab.
8. For better holding power, blow all dust and residue from the hole before driving
anchor into hole.
Place a flat washer over threaded end of anchor. Spin nut 1/2” down past end of anchor.
Carefully tap anchor into the concrete until nut and flat washer are against base plate. Do
not use an impact wrench to tighten.

INSTALLATION INSTRUCTIONS
1. Determine the location for the lift. Keep in mind overhead clearances. Sixteen feet is
the minimum recommended ceiling height. A higher ceiling may be required
depending the height of the vehicles. Standard dimension required for four post lift is
a minimum (SUPER-SHORT) 26’-1" x 37’-4”, (SHORT) 26’-1” x 42’-4”, (STD.)
26’-1” x 47’-4” or (EXT.) 26’-1” x 52’-4” bay area.
2. Unpacking lift, inspect lift for any damages due to transportation and check shipping
list for missing parts.
3. Determine which side of the lift the Control Console is to be installed. This is called
the MAINSIDE. The other side is referred to as the OFFSIDE. Ease of entry and
exit from vehicles, type of work being done and required placement of the console to
the lift are all considerations.
4. Step #1 Using the chalk line layout a rectangle were the leg assemblies will be
located (SUPER-SHORT) 17’-1 1/4" x 23’-5 ¾”, (SHORT) 17’-1 1/4” x 28’-5 3/4”,
(STD.) 17’-1 1/4” x 33’-5 3/4” or (EXT.) 17’-1 1/4” x 38’-5 3/4” bay area (see
Layout & Installation Specification sheet). This should give the lift 4” clearance in
front of the ramps and 7’-6 1/4” from the side of the any leg.
5. Step #2 After determining the Mainside, stand the two Mainside Legs upright inside
the chalk lines, with each leg facing inside. The two legs comes with two holes in the
bottom of the legs they should be facing the Control Console. (See Fig. #1 Layout
Drawing and Fig. #2.) Next level and anchor the Mainside Legs per the anchor tips
shown above.
6. Step #3 Unpack the inside of the leg by removing the wood blocks and chain straps.
Next run the hydraulic hose and ¼ airline tube thru the two holes with rubber
grommets in the legs. Do both legs the same way.
7. Step #4 Locate the LH and RH Cross Rails. Position the Cross Rail about 12” to 18”
from the Mainside Leg as shown in Fig. #2 and Fig. #10. Mainside end of the Cross
Rail in front of the Mainside Leg. Set each Cross Rail on two 4 x 4 blocks of wood.
Next connect the Cross Rail chains to the chain connector located at the base of the
Mainside Leg. There are two 2 ½” long dowel pins and one 3” long dowel pin inside
the chain connector held in place by dowel pin holders (See Fig. #2 & Fig. #13).
Remove the holders and slide the pins out. Connect the center chain first using the 3”
dowel pin then the outer chains using the 2 ½” dowel pins. Then bolt the RH/LH
dowel pin holders on the connector. Repeat procedure the other Mainside Leg.
8. Step #5 Slide the Cross Rail towards the Mainside Leg (See Fig. #3 & Fig. #10B).
The Cross Rail tube should be flush with the front part of the latch bar on the leg
weldment. Next connect the cylinder chain to the Cross Rail chain connector. There
should be two 4” long dowel pins in Cross Rail chain connector. Remove the holders
and slide the pins out. First connect the outside chain then the center chain. Then bolt
6

the RH/LH dowel pin holders on the connector to secure the dowel pins. Repeat
procedure the other Mainside Leg.
9. Step #6 Move the Offside Legs in front of the Offside end of the Cross Rail (See Fig.
#4, Fig. #10A). The end of the Cross Rail should be flush with the base plate of the
leg weldment. Next remove one at a time the safety latch pin keepers and replace it
with the safety rods. Next slide the Offside Leg into position. Look at your chalk line
layout. Once the leg is in position, pull the two safety rods thru the two holes. The
rods should stick out about 2” past the top plate (See Fig. #12). Screw and tighten the
1 ¼” Lock Washer and 1 ¼-7UNC Hex Nut. Repeat procedure the other Offside Leg.
Note the rectangular tube of the Cross Rail should be flush with the edge of the latch
bar welded on the Offside Leg.
10. Step #7 Locate the six round threaded chain connectors, 3/8” shoulder bolt and 5/16-
18UNC Nylon Hex Nut (See Fig. # 5 & Fig. #12). Attach the chain connector to the
chain and pull each thru the three holes on the top plate. Use vice grip pliers to hold
the bottom of the chain connector in place and a deep 1 11/16” deep socket to tighten
the jam nut. There should be about 1 ½” worth of threads past the first jam nut. May
have to adjust the chain connector depending on how level the lift is from side to side
with weight on the lift. Repeat procedure the other Offside Leg.
11. Step #8 Level and anchor the both Offside Leg. Anchor the Offside per the anchor
tips shown above.
12. Step #9 Locate and attach the rub block bracket as shown in Fig. #6. The rub block
brackets are also shown in Fig. #10, #10A & #10B. Raise Cross Rail about 24”, this
makes it easier to attach the brackets to Cross Rails. Mainside Leg uses the Single
Rub Block Bracket. The Offside Leg uses the Double Rub Block Bracket. Slide the
brackets in from the bottom and attach them using the 5/8 bolts, 5/8 lock washers and
the 5/8 flat washers.
13. Step #10 Locate and position the two Tracks in between the Cross Rail (See Fig. #1,
Fig. #7 & Fig. #11). Both jack rails on each Track should be facing each other. The
Track should be centered on the Cross Rail and should have a spacing of 3’-0” to 4’-
10” depending on the customer’s preference.
14. Step #11 Locate and position the two Ramps at the end of the Tracks (See Fig. #1,
Fig. #7 & Fig. #11). The Ramps can be placed on either end. The spacing between the
end of the Track plate and the Ramp should be about 3/8”. Next anchor Ramps using
the ½ anchor bolts.
15. Step #12 Locate and position the two Stops at the end of the Tracks (See Fig. #1, Fig.
#7 & Fig. #11). The Stops can also be placed on either end of the Tracks unless
Ramps are already anchored. Use ¾ bolts, ¾ flat washers, ¾ lock washers and ¾ nuts
to bolts Stops to the end plates of the Tracks.
16. Step #13 Locate and position the Control Console at centered between the two
Mainside Legs and a minimum of 2’-0” from the outside of the base plate (See Fig.
7

#1). Remove Top Console cover and attach hydraulic hoses and pneumatic tube as
shown in Fig.# 9.
17. Step #14 Next attach the 5/32” diameter coiled tube on the top tube connector in each
Mainside Leg to the pneumatic cylinders on the Cross Rails.
18. Step #15 Locate and position the hydraulic hose protectors as shown in Fig. #6.
Anchor protectors per anchor tips. Use 3/8 anchor bolts to secure hose protectors.
19. Step #16 Fill the power unit tank with AW-32 or equivalent hydraulic oil. Reservoir
has a 20-gallon capacity.
20. Step #17 Wire motor starter and motor (See power unit manual for installation).
21. Step #18 Raise lift and level Cross Rails side to side by adjusting the Threaded Chain
Connector on the Offside Legs. Cross Rails may have to re-adjust chain when load is
on the lift.
22. Step #19 Purge trapped air in hydraulic lines by raising and lowering lift repeatedly.
Refill tank with hydraulic oil and lift is ready to operate.
30 DAY MAINTENANCE
