If the plunger does not fully return the nail has not been completely driven. When this happens, use the
r
ubber face of the mallet to strike the top end of the metal plunger again. When the nail is completely driven
the ratcheting mechanism will allow the plunger to return.
Tool
As with any quality tool regular maintenance will improve its operation and life span. BOSTITCH
replacement parts are recommended. Do not use modified parts or parts which will not give equivalent
performance to the original equipment.
1. To inspect of replace any parts of the plunger, first remove the retaining clip and pull out the locking pin.
2. Pull out the plunger assembly.
3. Clean old grease, dirt and abrasive particles off of all parts.
4. Lightly grease the plunger and the plunger spring.
5. Replace all damaged or worn parts.
CAUTION: WHEN REPLACING THE DRIVER BLADE, ENSURE THAT THE WORD “FRONT” STAMPED
ON THE BLADE IS VISIBLE AFTER YOU HAVE INSTALLED IT ON THE PLUNGER.
Mallet
Over time the rubber face on the mallet may became worn, cracked, or chipped.These are signs that a new
rubber face will need to be installed.
Remove old rubber face:
1. Secure the rubber face in a bench vise.
2. Pull upward on the handle till the rubber face is released from the
steel stud.
To install a new rubber face on the mallet, we recommend doing it in
the shop with the use of an arbor press. If you must do it manually
follow these instructions.
1. Secure the mallet head in a bench vise.
2. Put the rubber cap slightly inclined on top of the steel stud, push
downward with a twisting motion to engage the rubber cavity
over the edge of the steel stud.
3. Once fully engaged over the edge, you can release the mallet
from the vise and hit it on solid surface to properly seat the rubber
face on the mallet head.
