Periodically clean and grease the axles
and moving parts of the Shop Crane
(F), which must always be clean and
protected from aggressive environments.
Only original spare parts should be used.
Before each use, check for bent, broken,
cracked or loose parts. Remove the Shop
Crane from service if you suspect it has
been subjected to abnormal loads or has
suffered a blow, until you have fixed the
problem.
The oil level needs to be checked or
continuously filled, remove the hydraulic
unit and the piston fully retracted,
remove the filler plug hole and empty
the contents into a bowl. With hydraulic
horizontally, proceed to introduce the
necessary volume. Avoid getting dirt
with the new oil.

kinematic at 40, or a viscosity of 3 Engler
at 50° C .
DO NOT USE BRAKE FLUID.
OPERATING INSTRUCTIONS
It is possible that air has got into the
hydraulic system, causing poor lifting
performance, purge any air from the
system by fully opening release valve

To lower load
• Open release valve by turning
handle very slowly, the speed of
lowering the load is controlled by
how much you turn the handle.
When the Shop Crane is not running, it
should be fully retracted in the lowest
position to minimize oxidation of the
piston.
We recommend applying an antioxidant
in both the main piston and in pump.
Keep the Shop Crane in a clean, dry
place.
