Monthly Maintenance

Periodically (approximately once a month) inspect the
ram guide sleeves, rods, and cylinders for wear or dam-
age; replace all worn parts.
Check the hydraulic fluid level. Add more hydraulic fluid
if the fluid level falls lower than 4 in. (102 mm) from the
top of the fluid gauge. See Checking the Hydraulic
Fluid Level, page 15.
Checking the Hydraulic Fluid
Level
Check the hydraulic fluid level in the supply unit. The
fluid level should be approximately 2–4 in. (51–102 mm)
from the top of the fluid level gauge (3). If necessary,
perform the following steps to add more hydraulic fluid:
1. Unscrew the breather (4).
2. Pour hydraulic fluid through the breather hole (13).
3. Replace the breather. See F
NOTE: Make sure hydraulic tank is filled to the correct
level. Overfilling tank can cause hydraulic fluid to spill
out the breather. See F
