If the plunger does not fully return the nail has not been completely driven. When this happens, use the rubber 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.
MAINTENANCE
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.
