RESULT: If the air does not pass through the cap, clean or replace the cap.
NOTICE: When checking for positive tank cap venting, air should pass freely
through the cap.
Using a mild solvent, carefully wash the cap venting system. Dry the venting system by
using low-pressure compressed air. Repeat vent check.
Install the breather cap onto the hydraulic tank.
The hydraulic tank is a vent-type tank. The breather cap has an internal air filter that can
become clogged or, or over time, can deteriorate. If the 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.
1. Remove and discard the hydraulic tank breather cap
2. 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.
1. Check the tire surface and sidewalls for cuts, cracks, punctures and unusual wear.
2. Check each wheel for damage, bends, or cracks.
