maintenance
Perform the cleaning work before inspection and maintenance
to prevent the dust from entering the machine and ensure the
maintenance can be securely performed.
If the machine is dirty when it is checked, it is difficult to locate
the fault, and there is the risk of dust and mud entering the eyes
or of the personal injury. Please obey the following items when
you clean the machine:
• Wear the shoes with anti-slippage heels to prevent from
slipping at the wet places.
• Wear goggles and work clothes when you clean the ma-
chine by using HP water gun.
• Adopt the protective measures to prevent HP water flow
from cutting skin or prevent the mud from entering the eyes.
• Do not sprinkle water directly onto the electronic compo-
nents (sensors, connectors) (1, Fig. 20). If the water enters
the electrical system, it will cause the failure or faults.
Pick up any tools in working area, rub up all lubrication oil, oil
and other lubrication substances, and clean the working area to
facilitate the safety operation. If the working area is not clean or
tidy, it will cause tumbling or injury.
