Sharpening Saw Chain - Remington RM1640W Manuel Du Propriétaire

CLEANING AND MAINTENANCE
Install Guide Bar
1. Place guide bar onto guide bar bolts (see Figure
20, page 17).
2. Place sprocket support over guide bar and secure
in place with E-ring (see Figure 20, page 17).
3. Place saw chain around sprocket, along top
groove of guide bar, and around guide bar nose
(see Figure 22). Note: Make sure cutting edges
of saw chain are facing in right direction. Position
chain so cutting edges on top of guide bar face
guide bar nose (see Figure 22 and indicator on
side cover of saw).
CAUTION: Do not place chain on saw
backwards. If chain is backwards, saw
will vibrate badly and will not cut.

SHARPENING SAW CHAIN

WARNING: Unplug chain saw from
power source before servicing. Severe
injury or death could occur from electri-
cal shock or body contact with moving
chain.
WARNING: Cutting edges on chain
are sharp. Use protective gloves when
handling chain.
Towards Guide Bar Nose
Cutting Edge
Guide Bar
Keep chain sharp. Your saw will cut faster and more
safely. A dull chain will cause undue sprocket, guide
bar, chain, and motor wear. If you must force chain
into wood and cutting creates only sawdust with few
large chips, chain is dull.
Items Needed to Sharpen Chain
Purchase these items from your local dealer, hard-
ware store, or chain saw supplies outlet.
• 5/32" round file
• Depth gauge tool
• File guide

• Medium sized flat file
Sharpening Cutters
Use file guide for 30° filing.
1. Adjust chain for proper tension (see Saw Chain
Tension Adjustment).
2. Clamp guide bar in vise to hold saw steady.
Note: Do not clamp chain.
3. Press 5/32" round file (attached to file guide)
into groove between top plate and depth gauge
on chain. File guide should rest on both top plate
and depth gauge (see Figure 23). Note: File at
midpoint of guide bar.

file guide is parallel to center of guide bar (see
Figure 23). This will insure that you file cutters
at 30° angle.
