TROUBLE SHOOTING
How to Check the Drill Scale After Installation
For the first test, lift the drill all the way up, to a level area. Put 200-250 pounds of weight on the right side,
then compare it to the left. Both sides should be within four to six pounds of each other.
•
If the weight is not within the four to six pound range, the drive chain might be too tight or the clutch is
binding. Loosen the chain and check the weight again.
•
If loosening the chain does not fix the problem, you must remove the clutch arm, and then check the
weight on both sides.
NOTE
: The clutch arm needs to be on the back of the clutch to work properly.
The second test is to lift the drill to a level area and zero the scale. Lift the drill up and down two to three times,
checking to see if the scale zeros out. Each time the scale is in the up position, it should be within four to six
pounds. If not, remove the clutch arm and repeat the test. If this solves the weigh problem, the clutch is
binding or it needs lubrication.
NOTE
: The clutch arm needs to be on the back of the clutch to work properly.
