Section 10 - Care of the unit
Although the maintenance responsibilities for equipment will vary depending upon
company policies, an alert operator can contribute greatly to the proper care of the aerial
device. The guidelines given in this section are for the hydraulic system, upkeep.
The observation and correction of minor maintenance problems, as they occur, may help
prevent costly repairs and reduce downtime. For a complete description of any
maintenance procedure, refer to the Maintenance Manual.
At no time should an aerial device be altered or modified without the specific written
approval from Posi-Plus Technologies Inc.
Hydraulic system
The condition of the hydraulic oil is the major factor in obtaining long life and trouble free
service from the pump, motor, valves, cylinders, seals, etc. in the hydraulic system.
Warning
Any oil added to the reservoir must be pre-filtered to ISO 14/12. To obtain this filtration
rating, use a filter with a

3
=200 rating.
The proper oil type, oil temperature, oil level, and oil cleanliness should be maintained by
following the guidelines recommended in the Maintenance Manual for top performance
from the hydraulic system. When cleaning the unit, care should be taken not to spray
water under pressure directly on or around the fill cap of the reservoir. This could spray
water inside the oil cap.
The minimum temperature at which oil will flow to the pump varies with the type of oil
used. The Maintenance Manual recommends hydraulic oil for various temperature
conditions. Regardless of the oil being used, cold weather start-up can damage the pump
quickly if the operator does not allow the oil to warm up before operating the unit.
Attention
Do not put the unit in service and run the pump at normal operating speeds until the
hydraulic reservoir feels warm to the touch.
The maximum temperature at which a hydraulic system can operate also depends to
some extent upon the hydraulic oil being used. Winter weight oil should not be allowed
to exceed 160°F (70°C) and summer weight oil should not be run over 180°F (100°C). If
an operator cannot hold his hand on the side of the reservoir momentarily before removing
it, the oil is reaching a temperature in excess of 150°F (66°C). If overheating occurs during
normal use, it could be an indication of a worn pump or other components, low oil level,
