ASSEMBLY AND WARNINGS
ABOUT THE GRINDING WHEEL
There are two types of grinding wheels, 1 / 8 "and 3 / 16" for sharpening chains from 1/4” to 3/8”pitch.
To replace or change grinding wheels:
Always disconnect from any power source
Remove blade protective shield, by removing screw at top of shield then pulling upward (straight up). You may need
to pull hard to remove.
See FIGURE#3 below for properly securing grinding wheels with plastic nut. Be sure plastic secure nut is assembled
in correct direction as per figure 3.
ALWAYS CHECK GRINDING WHEEL FOR ANY DAMAGE BEFORE USE
START-UP
FIRST: Check that you have proper size grinding wheel to match your chain.
Check your chainsaw CHAIN mfg specifications for proper wheel size, and/or refer to chart below.
Be sure the wheel is securely installed and ALWAYS check wheel for any damage BEFORE EACH USE.
NEVER use without wheel guard installed.
NEXT: Install the sharpener onto chainsaw chain bar, approximately centered.
- Notes: Always hit the STOP/RED off switch to stop the grinder. The provided power cables are complete with
terminals for quick and safe connection to any 12volt battery (SEE fig. 5). This allows the operator to use this sharpener
on-the-job or in-the-field, wherever a 12volt battery is available.

SHARPENING
ALWAYS clean the chain before sharpening
First:
Find the correct cutting angles needed by referring to chart provided. You will need your chain pitch and gauge. Refer to
your CHAIN mfg. specifications first, then use chart provided.
- Then adjust the cutting angle on the sharpener, using the black knob to obtain the correct angle.
- If possible, start grinding right-hand teeth first; starting from the worst tooth identified using the template/guide.
(SEE FIG. 4 – point D)
Next:
- Test your set-up before turning on the sharpener (BEFORE EACH USE)
- Tilt the wheel motor casing toward the operator, so the cutting part of the wheel slightly touches the tooth to
be sharpened
- Loosen the wing nut at the back of the sharpener, so the chain stop hits the back of the tooth
- Move the chain stop manually, so the wheel touches the tooth slightly for sharpening
(To adjust the amount of tooth that will be sharpened)
- Tighten the wing nut at the back of the grinder to keep chain stop in position.
READY TO SHARPEN:
Start the sharpener, slowly tilting the wheel towards the operator, to sharpen/work the first tooth;
- At this point, set the grinding depth by adjusting the wing bolt on the side of the grinder.
- After determining the amount of tooth to be sharpened, the wing bolt will be held in this position by a spring
- After completing above for the first tooth, complete all the “right” teeth
Once all right teeth have been sharpened, stop the grinder
- Rotate the grinder head to the same angle degree as the right side by loosening the black knob
- Stand near the side facing the bar, to avoid the any sparks caused by sharpening
- Position the rear part of a left tooth against the chain stop
- Start the grinder, slowly tilting the wheel towards the operator, to sharpen/work the tooth;
At this point, set the same grinding depth that was set for right teeth, by adjusting the wing bolt on the side of the grinder
- After determining the amount of tooth to be sharpened, the wing bolt will be held in this positioned by a spring
- After completing the above for first tooth, complete grinding of all the “left” teeth
NOTE: To avoid overloading the motor and to prevent the chain from being damaged, remove small amounts of material
and do not work too long on the same tooth, so you do not to damage the cutter (tooth). A good method is to pull the
sharpener blade to the tooth being sharpened two-three times before going to the next tooth.
Once sharpening is complete, turn off the sharpener, disconnect the cables from the battery or power source, remove the
sharpener from the Chainsaw Bar and place in a safe place out of the reach of children.
TROUBLESHOOTING
The grinder does not start:
- check that power supply is fully charged and cables are connected with no corrosion on battery.
- check that cables of the grinder are not damaged
The grinder’s electrical motor is overheated:
- check that the voltage indicated on the motor matches the battery (maximum 12volt battery)
- note that the maximum time (20 min.) is recommended for continuous motor operation
- check that grinding wheel is not blocked during grinding.
The direction of rotation of the wheel is the opposite of that indicated on the machine:
- check that your cables are properly connected to battery (positive / negative)
The machine shows signs of vibrations:
- check that the sharpener is secured to the bar of the chainsaw (motor-driven or electrical)
- check that the motor unit is secured to the base unit
- check that the grinding wheel is properly installed. Always check for cracked or broken blades.
If above problems persist, you may need to contact a local repair center or shop.

MAINTENANCE
- Always disconnect from power source before carrying out any maintenance, lubrication or cleaning operations
- Keep sharpener clean using a cloth rag with soap and water. Always dry after cleaning
ALWAYS keep safety labels clearly legible.
- NEVER use compressed air for cleaning, it can cause wood or metal dust to reach small areas in the sharpener causing
damage to essential components of the sharpener.
