Cold Weather Operation

WARNING:

 Read the section titled 

Important Safety Instructions 

at the beginning of this manual. Always wear eye and ear protection 
when operating this tool. Keep the stapler pointed away from yourself 
and others. For safe operation, complete the following procedures 
and checks before each use of the stapler.

When operating tools at temperatures below freezing, complete 
preparation procedures outlined above and follow the directions 
below.

1. Make sure compressor tanks have been properly drained prior to

use. Always drain the compressor tanks at least once daily while
using the stapler. This is especially important in cold weather
because any moisture in the air in the tanks will condense in the
cold temperature.

2. Keep the tool as warm as possible prior to use.
3. Lower air pressure to 80 psi or less.
4. Actuate the tool 5 or 6 times into scrap lumber to lubricate o-rings.
5. Turn pressure up to operating level (not to exceed 120 psi) and

use tool as normal.

Hot Weather Operation

Tool should operate normally. However, keep tool out of direct sunlight 

as excessive heat can damage bumpers, o-rings and other rubber 
parts.

MAINTENANCE

WARNING:

 

Disconnect air line from tool and remove fasteners 

from magazine before making adjustments or personal injury may 
result.

Daily Maintenance Chart

ACTION

Drain compressor tanks and hoses daily

WHY

Prevents accumulation of moisture in compressor and 
stapler

HOW

Open petcocks or other drain valves on compressor 
tanks. Allow any accumulated  water to drain from 
hoses

ACTION

Clean magazine, pusher, and contact trip mechanism

WHY

Permits smooth operation, reduces wear, and 
prevents jams

HOW

Blow clean with compressed air. The use of oils or 
solvents is not recommended as they tend to attract 
debris

ACTION

Before each use, check to ensure all screws, nuts and 
fasteners are tight and undamaged

WHY

Prevents jams, leaks and premature failure of tool 
parts

HOW

Tighten loose screws or other fasteners using the 

appropriate hex wrench or screwdriver

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. 

 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.
