Checking Cutter Placement
It is important that the cutter is not "thrown" when placed in the grinding position.
This is controlled by a resistance being applied by a magnet within the rear plate of the chain guide. Too fast a feed speed can cause the cutter to be thrown forward after the feed finger stops. Large chains are more prone -- slow down the feed speed should this occur.
The screw in the clamp plate (fulcrum screw) can be moved to allow for varying chain thicknesses.
Fit screw in right hand position for most small chains and in the left hand position for harvester chain.
Things to watch out for
· Check the grinding head for square and centre to the chain.
· Do not over tighten the chain clamp. Over tightening can damage the machine.
· Use the correct mode to suit the chain.
· Be careful to adjust the cutter sensor accurately. It should not be possible to make the LED on the end of the cutter sensor go out by moving the chain in the guide when the chain clamp is on. The sensor should not touch the cutter.
· Inspect chains for bent or broken cutters before sharpening. Do not use Auto mode on chains with bent or broken cutters.
· Damaged or burred drive links will cause inconsistent grinding and wear the machine. Repair drive links before sharpening.
· Regularly clean the machine. Grinding dust will rapidly build up on components causing premature wear and malfunction. When possible, use CBN grinding wheels as they do not emitt dust.
· In magnet mode, make sure the magnet is placed near to the proximity switch. It is necessary to place it on the side of a cutter as it dwells next to the proximity switch while the tooth is being ground and privides a longer signal.
· Ensure the grinding wheel runs true and is not damaged before switching on the grinder motor.
· Do not touch or pull the chain when operating the machine.
