Ryobi RY10520 Maintaining the Guide BAR, Mounting the SAFE-T-TIPNOSE Guard, See Figures 59

MAINTENANCE

MAINTAINING THE GUIDE BAR

See Figure 58.

CAUTION:

Make sure the chain has stopped before you do any work on the saw.

Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage.

Feathering or burring of the bar rails is a normal pro- cess of bar wear. Such faults should be smoothed with a file as soon as they occur.

A bar with any of the following faults should be replaced:

nWear inside the bar rails that permits the chain to lay over sideways

nBent guide bar

nCracked or broken rails

nSpread rails

Lubricate guide bars with a sprocket at their tip weekly. Using a grease syringe, lubricate weekly in the lubricating hole. Turn the guide bar and check that the lubrication holes and chain groove are free from impurities.

MOUNTING THE SAFE-T-TIP®NOSE GUARD

See Figures 59 - 60.

nStop the engine and disconnect the spark plug wire.

nMount the SAFE-T-TIP®on the bar nose.

nFit the locking tab in the recessed slot in the guide bar.

nTighten the mounting screw with wrench until snug.

nFrom the snug position, tighten the mount- ing screw an additional 3/4 of a turn using a wrench.
