MAINTENANCE
nAlways place the switch in the STOP “ O ” posi- tion before you work on the saw.
nMake sure the chain brake is not set by pulling the chain brake lever/hand guard towards the front handle to the run position.
NOTE: When replacing the guide bar and chain, always use the specified bar and chain listed in the Bar and Chain Combinations section later in this manual.
nWear gloves when handling the chain and bar. These components are sharp and may contain burrs.
nRemove the bar mounting nuts using the com- bination wrench provided.
nRemove the clutch cover and the outer guide bar plate.
nRemove the bar and chain from the mounting surface.
nRemove the old chain from the bar.
nLay out the new saw chain in a loop and straighten any kinks. The cutters should face in the direction of chain rotation. If they face backwards, turn the loop over.
nPlace the chain drive links into the bar groove as shown.
nPosition the chain so there is a loop at the back of the bar.
nHold the chain in position on the bar and place the loop around the sprocket.
nFit the bar flush against the mounting surface so that the bar studs are in the long slot of the bar.
NOTE: When placing the bar on the bar studs, ensure that the adjusting pin is in the chain ten- sion pin hole.
nReplace the outer guide bar plate ensuring that the bar pin groove is at the bottom with the upper and lower edges angled away from the guide bar.
