Precautions while performing service
NOTE: Only authorized personnel should service and
repair the truck.
Keep the truck clean
• Spilled oil, grease, scattered tools, etc, can cause
you to slip or trip. Always keep your truck clean
and tidy.
• If water gets into the electrical system, there is
danger that the truck may move unexpectedly
and/or damage to components may occur. Do not
use water or steam to clean any sensors,
connectors or the inside of the operator's
compartment.
• Use extreme care when washing the electrical
control cabinet. Do not allow water to enter the
control cabinet around the doors or vents. Do not
allow any water to enter the cooling air inlet duct
above the electrical control cabinet. If water
enters the control cabinet through any opening or
crevice, major damage to the electrical
components is possible.
• Never spray water into the rear wheel electric
motor covers. Damage to the wheel motor
armatures may occur.
• Do not spray water into the retarding grids.
Excess water in the retarding grids can cause a
ground fault, which will prevent propulsion.
Attachments
Place attachments that have been removed from the
truck in a safe place and manner to prevent them
from falling.
Working under the truck
• Always lower all movable work equipment to the
ground or to their lowest position before
performing service or repairs under the truck.
• Always block the tires of the truck securely.
• Never work under the truck if the truck is poorly
supported.
Rotating fan and belts
Stay away from all rotating parts such as the radiator
fan and fan belts. Serious bodily injury may result
from direct or indirect contact with rotating parts and
flying objects.
Adding fuel or oil
• Spilled fuel and oil may cause slipping. Always
clean up spills immediately.
• Always add fuel and oil in a well-ventilated area.
• When refueling, stop the engine and do not
smoke.
• Tighten the cap of the fuel and oil fillers securely.
• Never use fuel to wash parts.
Use of lighting
When checking fuel, oil, coolant or battery electrolyte,
always use lighting with anti-explosion specifications.
If such lighting equipment is not used, there is danger
of an explosion.
