OPERATION
WARNING:
Never clean, lubricate or adjust a machine that is in motion. Failure to heed may result in
serious personal injury or death.
COULTER BLADE WEAR
Blade wear can affect performance in loose trash conditions. Depth control and plugging problems can result. It may
be necessary to replace blades.
WARNING:
If required to service unit in raised position, be sure to install all transport lock pins. Failure
to heed may result in serious personal injury or death.
DANGER:
Inspect and replace worn or frayed hydraulic hose. Keep all connections tight. Escaping
hydraulic fluid under pressure can have sufficient force to penetrate the skin and cause serious personal
injury. Fluid escaping from a small hole can be almost invisible. Use a piece of cardboard or wood rather
than the hands to search for suspected leaks. Failure to heed may result in serious personal injury or death.
TRANSPORT ROLLER ADJUSTMENT
Check and adjust transport wheel rollers if necessary every
100 hours.
To adjust transport wheel rollers loosen ¾” roller bolts and
adjust ¼” bolts as necessary to eliminate transport wheel
wobble.
Ensure the rollers do turn when cart is raised and
lowered, then tighten the ¾” roller bolts.
Grease every 25 hours with general multi-purpose grease.
LUBRICATION
WARNING:
Never clean, lubricate or adjust a
machine that is in motion. Failure to heed may
result in serious personal injury or death.
Grease with general-purpose grease
There is a grease fitting on each transport frame guide roller and one inside the transport guide tube. This latter
fitting can only be greased when the transport pin has been removed and the unit has been completely lowered.
Grease every 25 hours.
Ensure that transport wheel rollers do turn when cart is raised and lowered. Adjust ¼” bolt as necessary.
Each coulter assembly has (2) grease fittings. Grease the fitting on the pivots weekly. Grease the hub four times per
season. Repack the hubs once per season.
There is a grease fitting on each end of the upper and lower parallel arms. Grease every 10 hours.
