Frequently Asked Questions - HI 750-T 1 Cocraft

What oil should I use for the air motor?

Use an easy-flowing, resin-free and acid-free oil with a viscosity grade of max 22, such as sewing machine oil or oil designed for air tools.

How often should I lubricate the hammer mechanism?

For occasional use (e.g., seasonal tire changes), pre-lubrication is sufficient. For daily use, lubricate the hammer mechanism 2-3 times per month with a few drops of engine oil via the screw hole.

Why is my impact wrench not delivering full power?

Possible causes: lack of lubrication (lubricate air motor), low air pressure (adjust to 6.3 bar/90 psi), wrong function selector position, or worn rotor blades. Check each.

What is the maximum operating pressure?

The maximum working pressure is 6.3 bar (90 psi). Exceeding this can cause the tool to explode.

Can I use regular sockets with this impact wrench?

No, only use impact sockets designed for impact wrenches. Normal sockets can shatter and cause injury.

How do I change the direction of rotation?

Use the function selector (6): turn clockwise for forward (tightening) with three impact settings; turn anticlockwise for reverse (loosening) with full impact force.

What should I do if water blows out of the exhaust?

Empty condensation from the air compressor tank and hoses. Water in the system can freeze or cause rust.

Is it safe to use the impact wrench in explosive atmospheres?

No, this tool is not designed for explosive atmospheres and is not insulated for contact with electric power sources.

How do I connect the impact wrench to the air supply?

Fit a quick-connect coupling to the air hose and a regular inlet nipple to the tool. Do not attach a quick-connect directly to the tool to avoid retained pressure.

What protective gear should I wear?

Always wear safety glasses and ear defenders. Also avoid loose clothing, jewellery, and tie back long hair to prevent entanglement.

Personal safety precautions

a) Pay attention to what you are doing and use common sense when using pneumatic tools. Never use any hand tool, pneumatic or power tool if you are tired or under the influence of drugs, alcohol or medication. One moment of inattention while using a power tool may result in serious injury.
b) Wear protective clothing. Always wear safety glasses. Using protective clothing such as dust masks, non-slip safety shoes, helmets and ear defenders when needed decreases the risk of injury.
c) Avoid accidental starts. Never hold your finger on the trigger when connecting the air hose or changing a socket.
d) Do not overreach. Make sure you stand steady and well balanced at all times. This will allow you to have more control in unexpected situations.
e) Wear suitable clothing. Do not wear loose-fitting clothing or jewellery. Keep hair, clothes and gloves away from moving parts. Loose-fitting clothes, jewellery or long hair could potentially become caught in any moving parts.
f) Dust extraction or collection equipment should be used whenever the work environment contains large amounts of dust.
g) Hold the product by its insulated gripping surfaces whenever using the tool where it could come in contact with hidden live wiring. Contact with live wires will make the metal parts of the tool live and could shock the user.
h) Avoid direct contact with accessories during use.

Projectile hazards

a) Parts of the workpiece, accessories or even the socket can fly off at high speed.
b) Always wear impact-rated safety eyewear when using the impact wrench. Select suitable safety eyewear that provides adequate protection for the task you are performing.
c) Ensure that the workpiece is securely fastened or clamped.

Entanglement hazards

a) Loose-fitting clothing, jewellery, necklaces or hair which becomes entangled with the tool could result in strangulation, constriction or crushing.
b) Gloves can become entangled in the rotating drive, resulting in severed or broken fingers.
c) Rubber-coated or steel-reinforced gloves can easily become caught in rotating sockets or extension bars.
d) Do not wear loose-fitting gloves or gloves with cut or frayed fingers.
e) Never hold onto the drive anvil, socket or extension bar.
f) Keep hands away from rotating drive anvils.

Connection to the air supply system

a) This tool must only be connected to a clean, filtered and dry air supply which provides an air pressure at the tool of 6.3 bar (90 psi). Warning: Too high a pressure will reduce the lifespan of the tool and could cause serious personal injuries.
b) Connect the tool to the air supply using a hose designed for high pressure air.
c) Fit a quick-connect coupling in the air hose and a regular inlet nipple onto the impact wrench. Do not attach a quick-connect coupling to the impact wrench itself, as this would retain pressure in the tool even when the air hose has been disconnected.
d) In order for the tool to work at its full capacity, the air compressor must provide the tool with at least the tool's rated air consumption.
e) Only use air hoses of the recommended dimension and length. Do not connect the tool to the air compressor without incorporating an easy to reach and operate air cut-off valve.
f) Make sure that any water which has condensed in the tank of the air compressor or the air hoses is emptied out regularly to prevent water being delivered into the tool. Water in the system could freeze in the hose or cause the tool to rust.

Lubrication

The air supply to the tool can be lubricated by connecting a mist-oiler into the air line or by applying a few drops of oil to the tool's air inlet nipple before connecting the air hose. The tool needs to be lubricated at different intervals depending on how often it is used.

Lubrication of the air motor

The impact wrench's air motor should be lubricated before initial use and before each subsequent use thereafter. Use an easy-flowing, resin-free and acid-free oil with a viscosity grade of max 22, such as sewing machine oil or oil designed for air tools and machines.

Disconnect the impact wrench form the air hose, hold the impact wrench upside down and drip 2–3 drops of oil into the air inlet (5). Do not apply too much oil; any excess oil will be sprayed out of the exhaust port. You should therefore hold a rag over the exhaust port and make sure that no people or sensitive objects are close by.

Lubrication of the hammer mechanism

The hammer mechanism is lubricated with grease before it leaves the factory and does not need to be additionally lubricated if the impact wrench is only used occasionally such as for spring and summer tyre changes. If the impact wrench is used daily, the hammer mechanism should be lubricated 2–3 times per month or whenever it is required.

Disconnect the impact wrench from the air hose. Remove the screw (2) using a 2.5 mm hex key and drip 2–3 drops of engine oil into the hole. Take care not to lose the O-ring located under the head of the screw. Screw the screw back in taking care not to overtighten and damage the O-ring.

1. When starting the impact wrench hold it in both hands (if possible) and pull the trigger.

Troubleshooting

The impact wrench fails to deliver full power or does not rotate at all.	The tool is unlubricated. Lubricate the tool with appropriate oil, refer to the Lubrication section.
	Low air pressure. Adjust the pressure regulator on the compressor to 90 psi/6.3 bar.
	The function selector is in the wrong position. Check and adjust.
	The pressure keeps falling. Air hose is too long or has too small a bore causing pressure drop. Check and replace it with a shorter hose or one with a larger bore.
	Worn/broken rotor blades in air motor. Replace.
	Water or spray blows out of the exhaust. Empty any condensation from the tank and hose.
	If the impact wrench has been left unused for a long time the rotor blades in the air motor might have stuck. Lubricate the tool with appropriate oil, refer to the Lubrication section. Then run the tool on High impact force for about 30 seconds. Refer to Operating instructions. If this doesn't help, repeat the procedure.
