) for cleaning
purposes. Clear the area of bystanders, guard
against flying chips, and wear personal protec-
tion equipment including eye protection.
IMPORTANT: When operating the machine in a dusty
environment, check the screen every
day for dirt and clogging. If clogged,
remove, clean and reinstall the screen.
1. Open the radiator access door and hood.
2. Clean the air conditioner condenser.
3. Remove the oil cooler front screen and clean it.
4. Clean both the radiator and oil cooler using com-
pressed air (Less than 0.2 MPa, 2 kgf/cm
2
) or water.
NOTE: Loosen 4 bolts (2 each on both sides) on the
condenser bracket to allow the condenser to
slide about 70 mm, making cleaning easier. Af-
ter cleaning, be sure to slide the condenser
back to the original position and re-tighten the
bolts (ZAXIS70, 70LC,80SB, 80SBLC, 80LCK).
