NOTICE:
Make sure that the work area and all equip-
ment is clean so that no dirt, dust or other foreign
materials can get into the hydraulic oil or pump area.
NOTICE:
Only use pure hydraulic oil recommended
by Makita. To prevent damage to the seals and other
internal machine parts, do not use other oil listed below.
Recommended oil:
•
Makita hydraulic oil
•
Super Hyrando #46 (JXTG Nippon Oil & Energy Corp.)
•
Shell Tellus Plus #46 (U.S. Shell)
•
Hydraulic oil with equivalent spec anti-wear, ISO
Viscosity Grade 46.
1.
Install the battery cartridge to the tool.
2.
Lay the tool on its left side so that the oil port is facing up.
3.
Operate the tool to move the punch position
almost to the bottom of its stroke.
NOTE: If necessary, run the tool for several strokes.
Doing so allows you to determine the bottom of stroke
and also position the punch piston correctly. In the
correct position, the maximum amount of oil has been
drawn from the pump and the appropriate amount of
oil for refill can be obtained.
4.
Remove the battery cartridge from the tool.
5.
Carefully remove the socket head cap screw to
open the oil port.
► 1. Socket head cap screw
6.
Fill the reservoir with hydraulic oil using the small
squeeze bottle which is supplied with the tool.
7.
Rock the tool back and forth slightly several times
to free any trapped air bubbles. After that, add addi-
tional oil as necessary.
8.
Replace the socket head cap screw and wipe up
any excess oil.
9.
Install the battery cartridge and run the tool for
several strokes with the return lever is in open position.
After that, run the tool again with the return lever is in
closed position.
Doing this purges trapped air out of the system. Repeat
this procedure to make sure that the punch piston is
almost at the bottom of its stroke.
10. Add additional oil as necessary by repeating step
3 to 9.
If the oil is depleted excessively, you need to repeat this
procedure several times.
