COATS 520 Wheel Lift - Manual (Page 9)

Routine Maintenance
The Coats Wheel lift does not need any special routine
maintenance. To ensure correct functional perfor-
mance and a long working life, lubricate the following
surfaces once a month with a silicone spray lubricant:
- the hex bar along which the clamps run, labeled
items 4 & 5 in Fig. H
- the hex runners inside the base
- the base wheels
When lubricating the machine also take the time to
clean the track that runs between the hex bars. Wheel
weights, debris, and hand tools can get between the
track.
Moving the Machine
Follow these steps if the lift has to be moved.
1. Disconnect the lift from the compressed air supply.
2. Unbolt the lift from the floor.
3. Move the upright, labeled item 6 in Fig. H, to its
limit stop.
4. Use a sling for the upright (minimum length 24")
putting it under the upper wheel clamp, labeled
item 4 in Fig. H, and inside the handle, labeled
item 2 in Fig. H, as shown in Fig. L.
5. Attach the ends of the sling to a hoist above the
lift. Hoist and move the lift using hoisting equip-
ment with adequate carrying capacity.
Storing
If the lift has to be stored for a long time:
1. Disconnect the lift from the compressed air supply.
2. Grease thoroughly:
- the hex bar along which the clamps run, labeled
items 4 & 5 in Fig. H
- the hex runners inside the base
- base wheels
3. Cover the lift with a plastic sheet.
Troubleshooting
Problem: When the toggle switch is moved upwards
the wheel is not clamped and raised.
Causes: Either there is not enough pressure in the
compressed air system or the air supply lines
are crushed or damaged.
Solution: Increase the supply air pressure to no more
than 145 psi and/or replace damaged air
lines.
