USING A RATCHET LEVER JACK
1 The operator should familiarize himself with the
jack, its capabilities and its operations. The revers-
ing lever (1) is located below the lifting mechanism
cover (2) on the left side of jack when viewed from
the lifting lever. When preparing to lift a load, the
head (3) can be pulled up by hand to meet the load.
2
To raise a load, pull reversing lever up and toward
the operator and operate the lever (4). The jack will
raise the load one notch for each lever downstroke.
The rack (5) cannot be ratcheted out of the base, as
it is designed to stop when raised to its top limit.
3
To lower a load, push reversing lever to straight-
down position and operate the lever. The jack will
lower the load one notch for each upstroke of the
lever.
4
When the head of the five-ton jack is not supporting
a load, the rack can be allowed to fall free by pres-
sing the reversing lever all the way to the rear and
slightly lifting up on the lifting lever. The rack will not
fall free if even a slight load is still on the head.
