1-Inch High Torque Impact Wrench Operator's Manual 

  

An automatic in-line filter-regulator-lubricator is recommended as it increases tool life 

and keeps the tool in sustained operation. The in-line lubricator should be regularly 

checked and filled with air tool oil. Proper adjustment of the in-line lubricator is 

performed by placing a sheet of paper next to the exhaust ports and holding the throttle 

open approximately 30 seconds. The lubricator is properly set when a light stain of oil 

collects on the paper. Excessive amounts of oil should be avoided. 

The oil reservoir in the anvil housing should be checked every 40 hours of operation. 

Remove the oil plug from the housing and hold tool so the oil port is lower than the anvil 

housing. Drain oil. Measure and refill with approximately 1 oz. (30 ml) of John Deere 

AT-4003 oil. Never overfill the anvil mechanism or excessive pressure will be created 

reducing tool speed and power. If the tool becomes sluggish after adding oil, remove a 

small amount of oil and check performance again.

In the event that it becomes necessary to store the tool for an extended period of time 

(overnight, weekend, etc.), it should receive a generous amount of lubrication at that 

time. The tool should be run for approximately 30 seconds to ensure oil has been 

evenly distributed throughout the tool. The tool should be stored in a clean and dry 

environment. 

Recommended lubricants:  Use John Deere AT-4003 air tool oil or any other high 

grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents 

and an EP (extreme pressure) additive.

Before the tool is connected to the air supply, clear the air hose of accumulated dust 

and moisture.  Before removing a tool for service or changing sockets, make sure the 

air line is shut-off and drained of air.  This will prevent the tool from operating if the 

throttle is accidentally engaged. 

This impact wrench has a built-in-power regulator, which can be adjusted by turning 

the valve counter-clockwise to increase and clockwise to decrease. The numbers on 

the dial are only for reference and does not note a specific power output.

Once a bolt or fastener is seated, impacting for longer than five seconds will cause 

excessive wear and damage to the impacting mechanism.  If it takes longer than five 

seconds to tighten your bolt or fastener, we recommend the use of a larger size impact 

wrench.
