CAUTION! Before performing any maintenance or disconnecting any hydraulic line, fitting or component, switch OFF the master disconnect switch except when checking hydraulic pressures. Wear work gloves and keep fingers clear. Failure to follow these safety precautions can lead to serious injury

NOTE! Check the fluid level in the oil reservoir tanks. Add oil as required. Clean strainer of any dirt or debris before adding oil

Oil filled to the bottom of the filler neck?

Checked the level more often than the prescribed 8 hour interval if saw use is heavy?

If the reservoir runs dry, manually applied oil to the stopped chain?

Refilled the reservoir and “primed” the oiler by cycling the bar up and down at least ten times?

NOTE! Use BIO-HY-GARD oil or an equivalent “All Season” high quality bio-degradable oil such as John Deere UP08142 Bar and Chain Oil;

NOTE! The bar’s groove depth must be sufficient for the chain’s straps and cutters to ride on the bar’s rails without drive links touching the bottom of the groove

Remove any imbedded particles or debris from the groove

If wear on the saw bar is beyond limits, chain sprocket pitch and alignment must be corrected

See “Inspect Sprocket Pitch Wear” for correction procedure

To minimize wear and damage to chain components and the guide bar, proper chain tension must be maintained

Chain tension should be tight enough that cutter bottoms are pulled firmly against the guide bar at all points around the perimeter of the bar

NOTE! Chain tension should be checked in the morning before shift

NOTE! Chain tension will change with heat. Any chain that is uncomfortably hot to the touch should be allowed to cool before re-tensioning

Chain tension tested by pulling the chain with thumb and forefinger at mid bar away from the bar

Chain tension adjusted if incorrect

Chain installed with the teeth properly oriented. The chain rotates from the bottom to the top of the bar in a clockwise direction as viewed in illustration. The sharpened edge of the cutting teeth must be positioned as illustrated
