WARNING:
THERE IS RISK OF SERIOUS PERSONAL INJURY TO THE SAW OPERATOR DUE TO THE CHAIN JUMPING OFF THE GUIDE BAR IF THE
SAW CHAIN IS NOT INSTALLED AND TENSIONED PROPERLY. FOLLOW ALL INSTALLATION AND MAINTENANCE INSTRUCTIONS IN
THIS SHEET AND THOSE IN YOUR CHAIN SAW OPERATOR'S MANUAL.
BAR & CHAIN MOUNTING INSTRUCTIONS
Wear gloves. With the chain saw off and cool, remove the old bar and chain. Install your new bar and chain as follows:
IMPORTANT: Standard PowerSharp® bars may not work on saws equipped for Intenz® bars. Before replacing an Intenz® bar with a stan-
dard PowerSharp® guide bar, check that your saw has a tensioning mechanism on the saw (see your saw operators manual).
1) Place the guide bar on the mounting studs.
2) Loop the new chain onto the drive sprocket with teeth cutting edges facing away from the drive sprocket along top edge of the guide bar.
3) Feed the chain into the groove of the bar and slide the bar away from the motor to remove slack from the chain. Adjust the position of
the bar adjusting pin until it engages the hole in the bar.
4) Replace the drive sprocket cover with the nuts and finger tighten.
IMPORTANT: The saw chain must be properly tensioned before using. See Tensioning Instructions below.
* To even bar wear and maximize bar life, invert the bar occasionally.
TENSIONING INSTRUCTIONS
1) With the bar-mounting nuts only finger tight, hold up the nose of the bar (FIG. A) and tighten the bar adjusting screw. (The location
of the adjusting screw varies. See your saw operator's manual.)
2) Tighten the bar-mounting nuts securely.
Chain tension is correct when, with some effort, with a gloved hand you are able to pull the chain smoothly around the
bar. The chain should touch the underside of the bar rail (FIG. B).
During early life use, run the chain around the guide bar, not cutting for a minute or two (for gasoline-powered saws, run at slow speed),
making sure the chain is getting a good supply of oil. Stop the motor and check the chain tension. If it has loosened, readjust.
After a short period of use, allow the chain to cool and once again recheck the tension. Watch tension carefully for the first half-hour and periodi-
cally throughout the life of the chain, readjusting as required when the chain and bar are cool to the touch. Never tighten chain when it is hot.
Lubricate your chain properly with good quality bar and chain lubricant. Make certain the chain is getting an adequate supply of oil – oil
should be thrown from the nose of the bar when running, but not in the cut. For gasoline-powered saws, you should use a full tank of oil
for each tank of fuel.
When cutting under very cold conditions, bar and chain oil may be diluted with up to 25-percent kerosene or diesel fuel to ensure an
adequate flow of oil.
USING THE BAR-MOUNT SHARPENER
The PowerSharp® bar-mount sharpener requires the installation of a genuine PowerSharp® sharpening stone prior to first use. The stone is
packaged with PowerSharp® chain and should be replaced with every new chain.
IMPORTANT: The PowerSharp® bar-mount sharpener is for use ONLY with PowerSharp® chain. NEVER attempt to sharpen other chain with
the bar-mount sharpener. Damage to the chain and sharpener will occur.
IMPORTANT: PowerSharp® chain uses unique top-sharpening cutters and can only be sharpened with a genuine PowerSharp® bar-
mount sharpener.
WARNING: ALWAYS WEAR PROTECTIVE CLOTHING, GLOVES, AND EYE PROTECTION WHEN USING THE SHARPENER.
INSTALL THE SHARPENING STONE
Unlatch the bar-mount sharpener cover by pulling up on the tip portion of the latch. Open the bar-mount sharpener cover (Fig. A) and insert
the stone into the mounting slot as shown (Fig. B). Ensure that the stone is completely seated to prevent loss during operation.
ATTACH THE BAR-MOUNT SHARPENER TO THE BAR
IMPORTANT: Always position arrow on bar-mount sharpener facing up.
WARNING: NEVER ATTACH OR REMOVE THE BAR-MOUNT SHARPENER WITH THE CHAIN SAW MOTOR RUNNING.
CAUTION: Always wear gloves when installing or removing the bar-mount sharpener and take care not to pinch fingers
when closing the sharpener cover.
1) Clean debris from the surface of the bar and the sharpener bar mounting area. 2) Unlatch and open the cover of the bar-mount sharpener.
3) With cover open and motor off, slide the two steel guide pins through the guide holes in the bar (Fig C) until the sharpener is flush against
the bar. 4) Close the cover until the longest pin is slightly protruding above the cover. 5) Securely latch the cover by pushing the tip of the
latch towards the sharpener cover until the latch clicks into position and is flush with the cover (Fig D).
WARNING: WHEN THE SHARPENER IS ASSEMBLED ON THE BAR, THE LONGEST PIN MUST BE VISIBLE ABOVE THE LATCH AND
THE LATCH MUST CLICK INTO PLACE. IF NOT, DO NOT USE THE SHARPENER. DO NOT USE THE SHARPENER IF ANY COMPONENT
IS BROKEN. SERIOUS PERSONAL INJURY COULD RESULT.
