(a)How to Refill Lubrication Cylinder
Raise the body and secure with body props.
Tailgate must be closed and locked in position.
Rotate the packer so that the lubrication cylinder is in a convenient access position, such as front street side.
Turn ignition off
To fill the reservoir, locate the grease fittings on the inside end and the ¼” grease line coming from the inside end of
the cylinder.
As you add grease, you must allow hydraulic oil to flow out the opposite end. This can be done in a number of ways:
1) With the packer in MANUAL mode to operate the tailgate, engine off but ignition switch on, hold down the
tailgate “down” control. While the valve is trying to lower the tailgate, the oil can flow out of the cylinder,
through the valve and into the tank
2) With the engine off, but ignition switch on and the PTO engaged, place a jumper wire from tailgate “down” to
the TO in the lower junction box
3) Hook up a temporary hose to the oil end of the lube cylinder and let it drain into the tank.
(b) Using a grease gun filled with NLGI 000 grease; fill the cylinder/reservoir from the grease zerk on the opposite end.
This grease is light and thin so that it can pass through lubrication lines.
(c) Disconnect the jumper line or reconnect the hydraulic hoses.
(d) Operate the tailgate open/close mechanism several times to check for leaks and broken hoses.
