HYDRAULIC LINES AND FITTINGS
Visually inspect the hoses and fittings for leaks, cracks, chafing or crimping. Since the
hydraulic system operates at high pressures, replace any components which are worn or
damaged before use.
HYDRAULIC FLUID RECOMMENDATIONS
•
The hydraulic oil level in the tank should be no lower than four inches from the top
which will be at the 80
°C line
of the tank. Check the oil level daily. Refill as required.
•
The low pressure filter in the system should be changed after the first 50 hours of
operation and changed every 250 hours thereafter. Under dirty or dusty conditions,
change the filter more frequently.
•
Recommended fluid-Chevron Hydraulic Oil AW ISO 32 or equivalent. For food grade
applications Chevron Hydraulic Oil FM ISO 32 or equivalent may be used.
DRIVE AND HYDRAULIC SYSTEMS
SUPPLYING POWER TO THE ELECTRIC MOTOR
Because there are various types of receptacles, truck beds equipped with electric motors
have the correct plug installed in the factory. Consult a qualified electrician to determine
the type and rating of plug needed and to have it installed if replacement is needed
(Figures 21, 22 & Table 1). If a longer cord is necessary, use a plug to make the
connection between the pigtail and the cord –
DO NOT
splice the conductors!
Figure 21- Motor Wiring Decal
You will also need to determine the appropriate size of extension cord needed for your
application. The lengths given in Table 1 are the maximum recommended length for
single-phase 220 VAC with a 2% maximum voltage drop.
Consult a qualified electrician
if your truck bed uses a motor other than a single-phase 7-1/2 HP motor for proper cord
sizes and lengths.
