breather cap is faulty or improperly installed, impurities can enter the hydraulic
system, which may cause component damage. Extremely dirty conditions may
require that the cap be inspected more often.
 Remove and discard the hydraulic tank breather cap
 Install a new cap onto the tank.
Bleeding air from the hydraulic system- System “lock”
It may be necessary to “bleed” air from the hydraulic system after service has
been performed. If the system is not free of air, the safety system will
activate and the “velocity fuse” in the manifold will “lock” the machine. This
lock can be over-ridden by pulling the manual release at the same time as you
raise the machine.
Please follow the following procedure:
1. Locate the hydraulic return line (located at the top of pump) 2. Remove line
and place this line in a container. 3. Pull (don‟t jerk) manual release (emergency
lowering valve located at the back of machine) and have an assistance raise
machine at the same time until oil comes out of the hose. (Usually takes about
two seconds) be careful as air and oil will exit the system with some velocity. 4.
Release manual release and raise lift. It will be necessary to add oil to the
system when the lift platform reaches ten feet of elevation. 5. Extend the
platform until it hits the cylinder stop (twenty-four feet) and reconnect the
hydraulic return line. 6. Lower unit and cycle system.
Tires and Wheels
Maintaining the tires and wheels in good condition is essential to safe operation
and good performance. Tire and/or wheel failure could result in a machine tip-
over. Component damage may also result if problems are not discovered and
repaired in a timely fashion.
