Timber Cat Head
Lubrication/Daily Checks (Figure Mnt-0007)
Lubricate the grease fittings on top of the blade bar every 4 hours. See Figure
Every 8 hours, lubricate the cylinder grease fitting through the top slot in the cover. See Figure Mnt-
0007. Every 8 hours, check all bolts and nuts for proper tightness. Tighten any bolt or nut found to be loose. Periodically check the hydraulic connections for oil leaks. Visually inspect the hoses for damage and replace as necessary. Periodically inspect blade stroke adjustment by running the head at normal operating speed (540 PTO) and checking that the upper and lower blades
Improper adjustment is also indicated by an abnormally high shock load on the hydraulic system during blade reversal. This is due to the hydraulic cylinder reaching its stroke limit, causing the pressure relief reversing components to engage. Continuous operation in this mode will result in oil overheating and premature failure of components. If the unit is improperly adjusted, follow the stroke adjustment procedures below.
Stroke Adjustment (Figure Mnt-0008)
Position the head in a safe area for operation. If necessary, barricade the head to prevent contact while it is being operated.
Remove the cover and loosen the two jam nuts (Item 1). See Figure
the hydraulic system due to the pressure relief reversing components being engaged. Continuous operation in this mode will cause premature component failure and hydraulic oil overheat. Once proper adjustment has been achieved, tighten the jam nuts (Item 1) and replace cover.
