Grinding Stumps; Adjustable Handle Freight - PowerTek 16-20 P Operation & Maintenance Manual

OPERATION

GRINDING STUMPS

1. Start the engine according to instructions
2. Use the throttle to gradually bring the RPM's up to full speed.
3. To move the stump grinder, gradually push the drive handle forward. Full handle forward is
walking speed. Pull back on the drive handle to travel in reverse.
4. Position the cutter wheel over the front edge of the stump and set the brake. You may need to
adjust the handle position for better leverage depending on the height of the stump.
5. Once you have maneuvered the stump grinder near a stump, turn the clutch switch on to
engage the cutter wheel. When the engine is cold, you may have to flip clutch switch off and
on quickly to keep the engine running.
6. Slowly lower the stump grinder until the wheel comes in contact with the stump. Move the
stump grinder back and forth in a long slow sweeping motion. Maintain the same elevation
until a section has been removed, then lower stump grinder to take out the next section and
continue until the front part of the stump is removed.
7. When the front part of the stump has been removed, release the brake and move the grinder
forward to the new edge, and reset the brake.
8. Repeat Steps 6 and 7 until the stump is completely removed. Do not exceed 12" below ground
level or 18" above the ground.
9. Turn the clutch switch off and wait for the cutter wheel to stop spinning before moving.
Important Note: For better performance and to avoid excessive clutch wear, run the engine at full
throttle during operation.
ADJUSTABLE HANDLE HEIGHT
The handle can be raised or lowered to provide different leverages to better handle
different stump heights. (Maximum stump height 18" above ground. Maximum
below ground cut is 12")
Shut off engine and wait for all moving parts to stop before adjusting handle.
TO ADJUST THE HEIGHT:
Holding the handle firmly, pull the handle lock pin to unlock the handle. Raise or lower the
handle as needed and let the lock pin slip back into one of the holes in the bracket.
To lock the handle in the towing position:
1. Remove the handle fold-up link from the info tube.
2. Push the handle all the way forward and hold it firmly in its upright position.
3. Slide the link (hole end) onto the handle lock pin and slide the other end (peg end) into the
topmost hole of the bracket.
4. Replace the hairpin cotters in the lock pin and link.
