Protect air lines from damage or pullcture.

Never point an air tool at oneself or any other parson. Serious injury could occur.

Check air hoses for weak or worn conditions before each use. Make sum all connections ate secure.

Release all pressure from the system before attempting to install, service, relocate or perform any maintenance.

Keep allnuts, bolts and screws tight and ensure equipment is in safe working condition.

air powered tool Always examine accessories before mounting for chips, cracks, or signs of damage.

Never use mounted points or other accessories that have been dropped or exposed to water, solvent or extreme temperature changes. It is a good practice to operate the tool ina protected enclosure for one minute after mounting any accessory.

Always use accessories with an RPM rating that meets or exceeds the tool

RPM taUng.

Never cany a tool by the hose or putl the hose to move the tool or a compressor. Keep hoses away from heat, oil and sharp edges, Replace any hose that is damaged, weak or worn.

Inhalation hazard: Abrasive tools, sj.__h as g#nders, sanders and cut-off tools generate dust end abrasive materials which can be harmful to human lungs and respiratory system. Always wear MSHA/NIOSH approved, properly rdting

face mask or respirator when using such tools.

SOme materials such as adhesives and

could cause serious injury with prolonged exposure. Always work in a clean, day, well ventilated area.

Air Tool

Before the tool is connected to the air supply, dear the air hose of accumulated dust and moisture by runn{ng air freely through the air hose for 5-10 seconds.

Air HoseS for yourAir Tools

Figure 1 Illustrates a recommended air hose hook up.

A 3/8 inch ID air hose is required up to a length of 25 feet. A 3/8 inch ID hose longer than 25 feet will cause a pressure drop and may impede performance. If more length is required, a ?? inch ID air hose is recommended. Be sure all hoses and fittings are the correct size and correctly secured before using the tool.

Hook Up

Never carry a tool by the hose or pu[I the hose to move the tool or a compressor. Keep hoses away from hea_, oil and sharp edges. Replace any hose thai is damaged, weak or worn.

Small (home) shop hard piping:

A piping diagram for a typical home shop is shown. Some helpful tips are:

???Always use hosesandpipesrated for

higherpressurethanyour Systemwill encounter,

Never use PVC pipes for compressed air piping systems as explosion and serious injury may result.

The connection from the compressor to the initial take-off herd pipe must

be a flexible hose in order to isolate

movement of the compressor.

Route the initial take-off line (pipe) as straight up the shop wall and as high as possible, This will help minimize water leaving the compressor and traveling through system

Slope the main lines down at least 3/4 inch per 10 feet of pipe away from air compressor; this will draw the condensate with the flow of air and away from the compressor.

Place the first drop as far from the compressor as the size of your shop wilt allow (50 feet is optimal, although unrealistic for a small shop). The further the drop, the more that condensation can occur, and the dher the air will be when it reaches the water separator.

In older to reduce the amount of water and contaminants that get into the water separator, install the take- offline on the top of the main air supply line for each air drop,

A Drain line should be placed at the end of the main line for condensate drainage.

Drain valves should be placed at the end of branch lines and the drain

line, and drained daily.

This tools features a power regulator ,a_zlve

(fig. 2). Rotate regulator untiJ desired output is achieved. The settings on the regu!etor

are only for reference and do not denote a

specific power output. Turn regulator to position with smaller circle being the least amount of power end largef circle being/or the most amount of power, The tool only operates at maximum power in reverse.

???ARNINGI

Once ,_bolt Or Pastener is seated,

Impacting for longer than five (5) seconds will cause excessive wear and possible damage to the Impacfing mechanism, flit takes longer than five seconds to tighten or loosen your bolt or fastener, we recommend the use of a larger size impact wrench.

Lubdcatien

An in-line filter-regulator-lubricator (fig 1) is recommended as it increases tool life ar_l keeps the tool insustained operation. The in-line lubdcalor should be mgulady checked and tiffedwith air loot oar. Proper adjustment of the ir_line lubltcator is performed by placing a sheet of paper next to the tools exhaust ports and holding the throttle open approxfmateiy 30 seconds. The lubricator is properly set when a light stain of oil COfleCISon Ihe paper.

Excessive amounts of oil should be avoided, fn 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 through the air inlet (Figure 3). The tool should be run for aptxoximatoly 30 seconds to ensure oil has been everdy distributed throughout the tool The tool should be stored in a clean and dry environment.

Recommended Lubricants

Use air leo; oi! or any other high grade turbine og co_ltaining moisture absorbent,

rust inh_itors, metal _et_ng agents and an EP (extreme pressure) addllive. See Figure 3 for lecalion/air inleL

IMPACT MECHANISM LUBRICATION The impact mechanism transfers power from the toot to a nut or bolt. Oil in the mechanism is forced out and must be replaced. Lubricate the impact mechanism one time a year, more

often If a tool is used more than ten hours a week.

To lub_qcateand clean the impact mechanism and the front bearing:

1.Disconnect the impact wrench from the air supply.

2.RRnlOvo the siol;ted screw or Allen head screw from the oil port hole (Ref, No. 51) (Refer to figure 3}.

3, Squeeze app_oxirrm.tely 1 oz. of 30 weight oil through the oil port hole. Replace the screw.

4.Reconnectthe air supplyto the impact wrenchand runfor 201o 30 seconds. Luixicate the entire impact mechanism by rotatingthe tool upsidedovm

end sidewayswh_ runningthe tool

5.Remove the screw and held the oil

port hole over a suitable container to allow excess oil to drain. S_n",etim'a,s

_ggefin9 the toof when dur_pang _e oils helps to lone out the excess oil

6.If the oil is di_3',repeat the procedureabove until the oil comes out de_'. Install the screw

and tighten. The residual oil remaining _ the impact mechanism chamber is aft that is needed for proper lubrication.

3b. Adjust the compressor regulator to tool maximum while the tool is running free

4. Tighten and seal hose fittings if leaks m'e found.

5a. 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" or larger depending on the total lenglh of the hose.

5b. Do not use 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.

1. Drain tank. (See air compressor manual). Oil tool and run until no water Is evident. Oil

too} again and run 1-2 seconds.

2a. Install a water separator/fitter.

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.

2b. Install an air dryer,

2c, Anytime water enters the tool, the tool

should be oiled immediately.
