r ■
—Using the saw properly and as recommended
in this manual.
—Maintaining correct Chain Tension, paged.
—Proper lubrication, page 10.
—Regular maintenance as described in this sec­

1. CHAIN MAINTENANCE
• Sharpen the chain when:
— Wood chips are smdil and powdery. Wood
chips made by the saw chain should be
about the size of the teeth of the chain.
— Saw has to be forced through the cut.
— Saw cuts to one side.
ICAUTION: I Always wear gloves when hand­
ling the chain. The chain can be sharp enough to
cut you even though it may be too dull to cut
wood.
a. CLEAN TREE SAP FROM THE CHAIN
BEFORE IT IS SHARPENED:
1 . ) Soak chain in a petroleum based solvent
or a detergent and water solution
2. ) Dry chain thoroughly.
3. ) Immerse the clean chain In light oil until oil
seeps into the rivet holes.
NOTE: Do not run a chain which has been
cleaned without lubricating it first.
b. SHARPENING INSTRUCTIONS
Items required:
Gloves
7/32” dia. file
6 ” file holder
4.) Sharpen cutters.
a. ) Support the square rod on the file holder
(with 7/32" round file) on cutter top plate.
Figure 30.
b. ) Hold the file holder level with the 30° guide
mark paraiieUo the center of the chain
and lower file handje 10 °. Figure 30.
c. y File from inside toward outside of cutter,

ZL WARNING
Maintain the proper hook angle according to the
manufacturer’s specification for the chain you are
using. Too much hook angle will increase the chance
of kickback which can result in serious personal
injury. Figure 33 & 35.
5.) Correct Depth Gauges
a. ) Place depth gauge tool over each cutter
depth gauge. Figure 34.
b. ) File level with the flat file If depth gauge is
higher than the depth gauge tool.
c. ) Maintain rounded front corner of depth
gauge with a flat file. Figure 34& 35.
NOTE: The very top of the depth gauge
should be flat with the front half rounded
off with a flat file.
