F. Inspect the tank vent: See Figure 3.13.
• The tank vent is drilled through the pipe plug.
• As the fluid moves from the tank to the cylinder,
it draws air in. As fluid moves from the cylinder
back to the tank, air is forced out of the tank.
• If the tank cannot "breathe" through the vent,
extending the ram will form a vacuum in the
tank.
• If the tank cannot "breathe" through the vent,
retracting the ram will pressurize the tank.
• The ram will move through part of its' stroke,
then stop as the vacuum or pressure builds.
• The vent also allows for the thermal expansion
of the hydraulic fluid.
If the tank is pressurized by a blocked vent, relieve the pressure by extending the ram before
attempting to remove the plug. Removing the plug from a pressurized tank can launch a danger-
ous projectile.
To check the tank vent:
• Remove the dip stick.
• Insert a piece of wire into the vent hole until it
comes out of the rivet that attaches the dip stick
to the plug. See Figure 3.14.
G. Replace the hydraulic oil filter:
• Turn the oil filter counter-clockwise to remove it.
• Coat the O-ring of the new oil filter with a light coat of oil.
• Thread the oil filter onto the oil filter housing hand tight
