OPERATING INSTRUCTIONS
1. Lock the boom in place for the proper weight marking
using the lock pin BEFORE APPLYING THE LOAD TO THE
LIFT. Do not exceed the rated capacity and travel limits
of the equipment.
2. Use appropriate levellers, slings or chains around the
load capable of sustaining the load before using the
hook to lift it. Make sure that the latching mechanism
is working properly before lifting or moving the load.
3. Once the load is securely hooked in place, lift the load
by turning the release valve clockwise until closed,
and pumping the jack until the load is clear of any
obstruction. Move very carefully avoiding slopes in
the direction of travel. Avoid sudden or swinging
movements of the load. To lower the load, turn the
release valve on the hydraulic jack counterclockwise
very slowly.
