GLOSSARY OF TERMS

PSI : Pounds per square inch; a unit of measure of pressure.
Bar: A metric unit of measure of pressure. One bar = 100kPa
PSIG: Pounds per square inch gauge
kPa : Kilopascal, 1000N/square meter

GETTING STARTED

Always operate , inspect and maintain this tool in accordance with all regulations (local , state , federal and country) that may apply to hand-held / hand-operated pneumatic tools
Be sure all hoses and fittings are the correct size and are tightly secured
Always use clean, dry air at 90 psig maxi mum air pressure. Dust , corrosive fumes and /or excessive moisture can ruin the motor of an air tool
The use of a hose whip is recommended. A coupler connected directly to the air inlet increases tool bulk and decreases tool maneuverabi Iity
For maximum performance, the coupler on the wall should be the next size larger than the coupler used on the tool. The coupler closest to the tool should not be less than the proper air supply hose size

Forward/reverse and speed control
The forward/reverse and speed control knob determines the direction of the tool and also serves as the variable speed control. To select forward rotation, depress the side button on the right side of the tool as shown. To select reverse, depress the side button on the left side of the tool as shown.

Forward rotation can be adjusted for variable speed by turning the button from low to high. For maximum forward torque, turn knob until the indicator line matches with ‘+’ symbol. For low forward torque turn knob until the indicator line matches ‘-‘ symbol.

Air Supply

The recommended hook-up is shown in the following illustration. Pneumatic tools operate on a wide range of air pressures. For maximum efficiency and longer tool life, the pressure of the air supplied to these tools MUST not exceed the rated
PSI at the tool when the tool is running. Using a higher than rated pressure will cause faster wear and drastically shorten the tool’s life. A higher air pressure can also cause an unsafe condition and explosion.
The inside diameter of the hose should be increased to compensate for unusually long air hoses 7.6 m. Minimum hose diameter should be 10 mm I.D. and fittings should have 6.35 mm NPT thread.
The use of air line lubricators and air line filters is recommended to prevent water in the line that can damage the tool. Drain the air tank daily. Clean the air inlet filter screen on at least a weekly schedule to remove accumulated dirt or other matter that can restrict air flow.
The tool’s air inlet used for connecting an air supply has standard 6.35 mm NPT American thread.

NOTE: An air filter unit should be placed between air compressor and air lubricator to promote clean air supply to the impact wrench. Water, dirt, and scale can damage the impact wrench.

Prepping the Air Tool

WARNING: Risk of unsafe operation. Firmly grasp air hose with hand when installing or disconnenting to prevent hose whip.
WARNING: Risk of bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer’s maximum pressure rating for air tools and accessories. The regulator output pressure must never exceed the maximum pressure rating.

Drain water from air compressor tank and condensation from air lines. (Please refer to air compressor’s operation manual.)
Lubricate the tool. (Please refer to the Maintenance section in the manual.)
Connect the air ratchet to air source with the hose of recommended size.

Proper Hand Position (Fig. A)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position.
WARNING: To reduce the risk of serious personal injury,
ALWAYS hold securely in anticipation of a sudden reaction.

OPERATION

WARNING: To reduce the risk of serious personal injury, turn unit off and remove air supply before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

Operating Procedures

Air Supply

CAUTION: This air tool requires lubrication BEFORE initial use, also before and after each additional use. WARNING: Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 PSI/6.2 bar when the tool is running with the trigger fully depressed.

Use recommended hose size. It is recommended that the tool is connected to the air supply.
Do not connect the tool to the air line system without incorporating an easy to reach and operate air shut off valve. The air supply should be lubricated. It is strongly recommended that an air filter, regulator, lubricator (FRL) is used as this will supply clean, lubricated air at the correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such equipment is not used then the tool should be lubricated by shutting off the air supply to the tool and then
depressurizing the line by pressing the trigger on the tool. Disconnect the air line and pour into the air inlet 1 teaspoon of a suitable pneumatic motor lubricating oil, preferably incorporating a rust inhibitor. Reconnect tool to air supply and run tool slowly for a few seconds to allow air to circulate the oil.
Lubricate tool daily if used frequently, or when it starts to slow or lose power.

Start‑Up (Fig. A)

Turn on the air compressor and allow the air tank to be filled.
Set the air compressor regulator to 90 PSI (6.2 Bar) This air tool operates at a maximum of 90 PSI (6.2 Bar) air pressure.
Depress the Variable speed trigger 1 to start operating the tool. The more you squeeze the trigger, the faster the tool will operate.

Shut‑Down (Fig. A)

Release the Variable speed trigger 1 in order to stop the tool.
When changing accessories, always disconnect air supply to avoid injury.
When job is completed, turn off the air compressor and store the air tool after lubrication.

Operating Instructions

Securely fit the socket or attachment to the impact wrench.
Place the Forward/Reverse and speed control switch in the correct position for tightening or loosening the fastener.

Continuous satisfactory operation depends upon proper tool care and regular cleaning.

MAINTENANCE

Your Mac Tools power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

Lubrication

CAUTION: This air tool requires lubrication BEFORE initial use, also before and after each additional use.
WARNING: Keep out of the reach of children. If air tool oil is ingested, do not induce vomiting, call a doctor immediately.
WARNING: Any excess oil in the tool is immediately expelled from the exhaust port. Always direct exhaust port away from people or objects.

Air tools require lubrication throughout the lifetime of the tools. This power tool uses compressed air as a power source. The compressed air contains moisture that will rust the components inside of the tools, therefore lubrication is required daily. Failure to lubricate the air tool properly will dramatically shorten the life of the tool and will void the warranty
Always use an air line lubricator with this tool. After every eight hours of operation, if a lubricator is not used on the compressed air network, inject 1/2 to 1 cc of approved air tool oil (Mac Tools part #PO32) through the tool’s inlet connection.
After every forty-eight hours of operation, or as experience indicates, inject about 4 cc of approved pneumatic grease (Mac Tools part #PNG16) into the grease fitting.

To lubricate the air tool manually

Disconnect the tool from the air supply source, place the air inlet face up.
Depress the trigger and place about 5 to 10 drops (0.25 to 0.5 ml) of air tool oil into the air inlet.
NOTE: Use SAE #10 weight oil if air tool oil is not available.
Remove accessory, connect the tool to an air source, then cover the exhaust end with a towel and run tool for 2 to 3 seconds.

To lubricate internal mechanism
Locate the grease fitting in the back of the tool. Inject 4 cc’s of MAC tools approved impact grease into the fitting every 3-6 months depending on use.

NOTE: Check the speed and make a simple check of the vibration level after each service.

Storage
Store pneumatic tool and accessories in a dry, safe place. The air tool must be lubricated before storing.

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 procedure.
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.
