Instructions (Continued)

Storage

The impact wrench must be lubricated before storing. Follow the air motor lubrication instructions with an exception to step 4. Only run the impact wrench for 2 to 3 seconds instead of 20 to 30 seconds because more oil needs to remain in the impact wrench when storing. The tool should be stored in a cool dry place.

Troubleshooting Chart

Stop using tool immediately if any of the following problems occur. Serious personal injury could occur. Any repairs or replacements must be done by a Qualified Service Person or Authorized Service Center.

Symptom

Possible Cause(s)

Corrective Action

Tool runs slowly or will not

1. Grit or gum in tool

1.

Flush the tool with air tool oil, gum solvent,

operate

 

 

 

or an equal mixture of SAE 10 motor oil

 

 

 

 

and kerosene. If air tool oil is not used,

 

 

 

 

lubricate the tool after cleaning

 

2.

No oil in tool

2.

Lubricate the tool according to the

 

 

 

 

lubrication instructions in this manual

 

3.

Low air pressure

3.

a. Adjust the regulator on the tool to

 

 

 

 

 

the maximum setting

 

 

 

 

b. Adjust the compressor regulator to tool

 

 

 

 

 

maximum while the tool is running

 

 

 

 

 

free

 

4.

Air hose leaks

4.

Tighten and seal hose fittings if leaks are

 

 

 

 

found

 

5.

Pressure drops

5.

a.

Be sure the hose is the proper size.

 

 

 

 

 

Long hoses or tools using large volumes

 

 

 

 

 

of air may require a hose with an I.D.

 

 

 

 

 

of 1/2 inch or larger depending on the

 

 

 

 

 

total length of the hose

 

 

 

 

b.

Do not use a multiple number of hoses

 

 

 

 

 

connected together with quick connect

 

 

 

 

 

fittings. This causes additional pressure

 

 

 

 

 

drops and reduces the tool power.

 

 

 

 

 

Directly connect the hoses together

 

6.

Worn ball bearing in motor

6.

Remove and inspect bearing for rust, dirt

 

 

 

 

and grit or worn race. Replace or clean and

 

 

 

 

regrease bearing with bearing grease

 

 

 

 

 

Moisture blowing out of tool

1.

Water in tank

1.

Drain tank. (See air compressor manual).

 

 

 

 

Oil tool and run until no water is evident.

 

 

 

 

Oil tool again and run 1-2 seconds

 

2.

Water in the air lines/hoses

2.

a.

Install a water separator/filter.

 

 

 

 

NOTE: Separators only work properly when

 

 

 

 

the air passing through the separator is

 

 

 

 

cool. Locate the separator/filter as far as

 

 

 

 

possible from the compressor

 

 

 

 

b.

Install an air dryer

 

 

 

 

c.

If the original separator will not

 

 

 

 

 

separate all the water from the air,

 

 

 

 

 

install a belt air filter
