onto the tool while making fastenings, check the tool
frequently to be sure the muzzle bushing and load strip
track are clear.
Use of Partially Used Load Strips
The design of the 52051 is such that the next load to
be fired is manually indexed into the firing position by
compressing the load strip advancement lever
tool opening sequence of operation. If it is necessary to use
a partially used load strip, the end of the strip containing
the live loads should be placed into the bottom of the tool
handle just as if it were a new strip. By counting the number
of unfired loads in the strip before inserting it and keeping
count as the fastenings are being made, one can easily
determine when all of the loads have been used.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, remove loads and fasteners before
making any adjustments or removing/installing
attachments or accessories. An accidental
actuation can cause injury.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this procedure.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non‑metallic parts of
the tool. These chemicals may weaken the plastic
materials used in these parts. Use a cloth dampened
only with water and mild soap. Never let any liquid
get inside the tool; never immerse any part of the tool
into a liquid.
Clean the tool daily. Always make sure the tool is not loaded
before performing any service or repair and always wear
safety goggles when cleaning or servicing the tool.
Normal Cleaning
All front end parts shown in the disassembly section are
to be cleaned daily with a good detergent oil and wire
brush. Remove all dirt and carbon buildup and wipe parts
dry with a clean rag. Check all parts for wear or damage
before reassembly and replace or repair any worn or
damaged parts.

Maintenance
Heavy or constant exposure to dirt and debris may require
that the tool be cleaned more extensively. Complete
disassembly and cleaning of all parts may be necessary to
restore the tool to normal operation. General maintenance
should be performed every six months or more often if the
tool is subjected to heavy use. Contact your authorized
D WALT distributor for assistance.
