and lubricate the chain (Fig. 16).
Chain Sharpening
m
WARNING!
To ensure that the saw works safely and
effectively, it is essential that the cutting components are
well-sharpened. It is highly recommended to replace the
chain once it loses its ability to cut cleanly and safely. It
is however, possible to sharpen the existing chain if carefully
performed. Any work on the chain and bar requires specific
experience and special tools. For safety purposes, we
recommend you contact an authorized Snow Joe

+ Sun Joe

dealer or call the Snow Joe

center at 1-866-SNOWJOE (1-866-766-9563).
Sharpening is necessary when:
• Sawing creates sawdust instead of wood chips
•
Cutting
becomes difficult
•
The saw does not cut straight
• There are excessive
vibrations
A professional service center will sharpen the chain using the
right tools to ensure minimum removal of material and even
sharpness on all the cutting edges.
If you decide sharpen the chain by yourself, it's recommended
to purchase the Sun Joe

24V-CSSHRP-LTE chain saw
sharpener, which can be powered by the same iON+ 24V
battery that comes with this cordless pruning saw. Visit

Manual Chain Sharpening Tools
(not included)
To sharpen the chain manually, you will require the following
tools.
• 5/32 in. (4 mm) round file
• File guide
• Flat file
•
Depth gauge tool
• Felt-tip marker
Manual Chain Sharpening Procedure
1. Tighten the chain if loose. Then secure the guide bar in a
vice or clamp.
2. Mark one of the cutters on the top of the guide bar with a
felt-tip marker to indicate where you started.
3.
Insert your round file into the file guide.
4.
Place the file and file guide into the cutter at a 30
° angle.
Then file in a forward motion in 5-6 even strokes, while
maintaining the file at the correct angle and parallel to
the ground until the cutting edge of the cutter is shiny
(Fig. 31).
NOTE:
Most file guides have 30
° and 35° angles etched
on their upper side to help you preserve the angle as
you file.
5. File every cutter on one side of the chain until you reach
the one you marked before turning the saw over on the
other side to sharpen the rest. Use gloves or a screwdriver
to advance the chain as you progress from one cutter to
the other (Fig. 32).
NOTE: File the cutter on the opposite side of the chain if
right handed or file the cutter on your side if left handed.
