1.4. Safety instructions for maintenance
Follow the manual
Follow the instructions in the manual for inspection and maintenance. In
particular, pay special attention to safety alerts and do not rush. Accidents
during maintenance are mostly attributed to negligence of the guidelines.
Completely stop the carrier
Inspection and maintenance should be done, after completely stopping the excavator on an even and safe
surface, with all control levers and switches on safe position.
Use proper tools
Use proper tools for inspection and maintenance. If you carry out any inspection or maintenance work using
improper tools, it may result in personal injury or damage to product.
Pay attention to hydraulic system
Draw special attention to maintain hydraulic system. Even though it is stopped,
the inside of a hydraulic system that has been operated can be hot. So, do not
disassemble it rashly. Be sure to remove the pressure left inside the hydraulic
device, close the lock and prevent any external forces from being applied to the
device according to a maintenance guide, before maintain it. For the compactor
cylinder in particular, there may be pressure left in the system even after the
compactor stops, and it may be exploded when it is disassembled. Therefore, be
sure to follow the disassembly order.
If there is a tiny hole or crack in the hydraulic device, pressurized fluid may
spout from it, to injure people near it. Fluid that spouts lightly may not be seen
by the naked eye. In this case, check the leakage using a sheet of paper or a
wooden board, wearing eye protection.
Right after operation, fluid is very hot. So, you have to be careful not to get
burned. In addition, as air inside the oil tank of the excavator is compressed, a
large amount of hydraulic oil may gush out if the hydraulic line connected to the
oil tank is disassembled. So, open the filler-cap slowly to remove the
compressed air from the oil tank before disassemble the hydraulic device.
Remove oil from the floor
When there is oil on the floor, it may result in an accident. So, when you spill or drop oil on the floor, wipe it
out immediately
.
Do not alter or modify
Unauthorized product modification or attachment of any unauthorized accessories can cause very dangerous
accidents. In addition, use of non-genuine parts can result in accidents or product damages. Therefore, use
our genuine parts only.
