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.
Other lubrication
Grease fittings are provided on both the top and bottom ends of the main hydraulic cylinder.
Lift the machine and place the safety prop in position in order to grease these fittings.
Alarms (a horn in control box and a red light on platform)
Outrigger proximity and pressure switches- Audible/Visual alarm
Occasionally it may be necessary to adjust outrigger proximity and pressure switches. The
proximity switch is a “normally closed switch which opens into a depression in the outrigger. You
can easily locate this depression on the outrigger. The pressure switch is a normally open switch
which closes as the outrigger jack is deployed downward and comes in contact with the ground. If
the proximity switch is in the correct position for operation of the lift a green LED will light in the
corresponding position as the leg.
The switches are the same part number and can be interchanged. They are adjusted by
loosening two screws on each side of the switch cover. The proper adjustment is noticed by hearing
a “click” when each switch is activated or deactivated.
Level sensor- Audible/Visual alarm
The level sensor is designed to give an audible signal at out of level attitudes of 3 degrees
front to back and 2 degrees side to side. The level sensor is pre-set at the factory and it is leveled
with the frame of the machine using three bracket bolts with spring tension on them. Always level
the machine to the frame using both the indication level on the sensor and a four foot contractor’s
level.
The lifts with auto-level will automatically level the lift to much less than 2 degrees.
