Safety Precautions
CAUTION: To prevent personal injury and damage to equipment,
•
Read, understand, and follow all instructions, including the ANSI B30.1 safety code for jacks. Before
using the fork lift jack to lift a vehicle, refer to the vehicle service manual for recommended lifting
surfaces on the vehicle chassis.
•
Wear protective eyewear that meets the requirements of ANSI Z87.1 and OSHA.
•
Inspect the jack before each use; do not use the jack if it’s damaged, altered, or in poor condition.
•
Use the jack for lifting purposes only.
•
A load must never exceed the rated lifting capacity (4 ton) of the jack.
•
Only use the jack on a hard, level surface.
•
Do not tilt the vehicle more than 15
°
when using the
serrated pad. Tilting the vehicle too far may result in
the jack kicking out suddenly and dropping the load.
•
Stay clear of lifted loads and the scissor mechanism
of the jack.
•
Place support stands under the axles before working
on the vehicle. See Figure 1.
•
Do not modify the jack or use adapters unless
approved or supplied by OTC.
•
Lower the jack slowly and carefully while watching
the position of the jack saddle. Do not drive the fork lift truck off the jack, or move the fork lift when
it is supported by the jack.
•
Use only approved hydraulic fluid (Mobile DTE #13 or equivalent). The use of alcohol, hydraulic brake
fluid, or automatic transmission fluid (ATF) could damage seals and result in jack failure.
This guide cannot cover every situation, so always do the job with safety first.
Figure 1
Bleeding Air from the Fork Lift Jack
Air can accumulate within a hydraulic system during shipment or after prolonged use. This entrapped air causes
the jack to respond slowly or feel “spongy.” To remove the air:
1. Open the release valve (large knob on top) by turning the knob two full turns counterclockwise (CCW).
2. Pump handle slowly 5 –10 times.
3. Close release valve.
If jack does not lift correctly, repeat steps 1 through 3.
