 WARNING

Always wear eye protection with side shields marked 

to comply with ANSI Z87.1. Failure to do so could 

result in objects being thrown into your eyes resulting 

in possible serious injury.

 

 WARNING

Disconnect the tool from the air supply before 

performing maintenance. Failure to do so could result 

in serious personal injury.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most 

plastics are susceptible to damage from various types of 

commercial solvents and may be damaged by their use. 

Use clean cloths to remove dirt, dust, oil, grease, etc.

 

 WARNING

Do not at any time let brake fluids, gasoline, petroleum-

based products, penetrating oils, etc., come in contact 

with plastic parts. Chemicals can damage, weaken or 

destroy plastic which may result in serious personal 

injury.

LUBRICATION

Frequent, but not excessive, lubrication is required for 

best performance. Oil for pneumatic fastening tools 

added through the air line connection will lubricate the 

internal parts. Do not use detergent oil or additives as 

these lubricants will cause accelerated wear to the 

seals and bumpers in the tool, resulting in poor tool 

performance and frequent tool maintenance.

COLD WEATHER OPERATION

For cold weather operation, near and below freezing, 

the moisture in the air line may freeze and prevent tool 

operation. We recommend the use of air tool lubricant or 

permanent antifreeze (ethylene glycol) as a cold weather 

lubricant.

 

 CAUTION

Do not store tools in a cold weather environment to 

prevent frost or ice formation on the tools’ operating 

valves and mechanisms that could cause tool failure.

NOTE: 

Some commercial air line drying liquids are 

harmful to “O” rings and seals. Do not use these low 

temperature air dryers without checking compatibility.

AIR SUPPLY PRESSURE AND VOLUME

Air volume is as important as air pressure. The air 

volume supplied to the tool may be inadequate because 

of undersize fittings and hoses, or from the effects of dirt 

and water in the system. Restricted air flow will prevent 

the tool from receiving an adequate volume of air, even 

though the pressure reading is high. The results will be 

a slow operation, misfeeds or reduced driving power. 

Before evaluating tool problems for these symptoms, 

trace the air supply from the tool to the supply source 

for restrictive connectors, low points containing water and 

anything else that would prevent full volume flow of air 

to the tool.

REQUIRED DAILY CHECKLIST
See figure 18 - 19.

1.  Disconnect the air supply from the tool and remove 

all fasteners.

2.  Check all screws, nuts, bolts, and pins on the tool. If 

any of these are loose, they must be tightened with 

the appropriate size wrench.

3.  Press the workpiece contact against a workpiece to 

ensure that it moves smoothly.

4.  With the workpiece contact depressed, pull the 

trigger. The trigger should move smoothly, without 

binding.

5.  While the tool is not loaded, connect the appropriate 

air supply 4.8 bar (70 psi) to the tool.

6.  Rotate the selectable trigger knob on the trigger to 

single sequential actuation operation, position A 

(See 

figure 18)

. No air should leak from the tool.

 

Without pulling the trigger, press the workpiece 

contact against a workpiece several times. The 

tool must not operate.

 

With the workpiece contact not engaged on the 

workpiece, point the tool down and away and pull 

the trigger several times. Hold the trigger in this 

position for a minimum of 5 seconds. The tool 

must not operate.

 

Press the workpiece contact firmly against the 

workpiece. Pull the trigger. The tool must operate.

 

With the workpiece contact still depressed, 

release the trigger. The driver must return to its 

up position.

7.  Rotate the selectable trigger knob on the trigger to  

contact actuation operation, position b 

(See figure 19)

.

 

With the workpiece contact not engaged on the 

workpiece, point the tool down and away. Pull the 

trigger. The tool must not operate.

 

Keeping the trigger fully depressed, push the 

workpiece contact against a workpiece. The tool 

must operate.

8.  If the tool successfully meets all the requirements in 

this checklist, it is ready for use. Set the trigger on 

the tool to operate in the manner that best fits your 

application. Load the proper fasteners for the desired 

application.

Note:

 Do not use this tool in the contact actuation 

mode unless you have had training in the use of 

this mode of operation. Untrained or inexperienced 

operators should not use the contact actuation mode.

9.  Set the depth of drive according to the 

drive depth 

adjustment

 section in this manual. Repeat this 

checklist before using the tool each day, or if the tool 

is dropped or damaged in any way.

REPLACING THE WIRE DEFLECTOR
See figure 20 - 21.

Over  time,  the  wire  deflector  will  wear  and  should  be 

replaced.
