Ergonomic guidelines

Consider your workstation as you read through this list of general ergonomic guidelines and see if you can identify areas for improvement in posture, component placement, or work environment.

• Take frequent breaks and change work positions frequently.

• Adapt the workstation area to your needs and the work task.

  • Adjust for convenient reach range by determining where parts or tools should be located to avoid static load.

  • Use workstation equipment such as tables and chairs appropriate for the work task.

• Avoid work positions above shoulder level or with static holding during assembly operations.

  • When working above shoulder level, reduce the load on the static muscles by reducing the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.

  • Make sure to take frequent breaks.

  • Avoid extreme arm or wrist postures, particularly for operations requiring a degree of force.

• Adjust for convenient field of vision by minimizing movement of the eyes and head during the work task.

• Use the appropriate lighting for the work task.

• Select the appropriate tool for the work task.

• Use ear protection equipment in noisy environments.

• Use high-quality inserted tools or consumables to minimize exposure to excessive levels of vibration.

• Minimize exposure to reaction forces.

  • When cutting:

    A cut-off wheel can get stuck if the wheel is either bent or if it is not guided properly. Make sure to use the correct flanges for cut-off wheels and avoid bending the wheel during cut-off operation.

  • When drilling:

    The drill might stall when the drill bit breaks through. Makes sure you use support handles if the stall torque is too high. The safety standard ISO11148 part 3 recommends using something to absorb the reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.

  • When using direct-driven screw or nutrunners:

    Reaction forces depend on tool setting and joint characteristics. The ability to bear reaction forces depends on the operator’s strength and posture. Adapt the torque setting to the operator's strength and posture and use a torque arm or reaction bar if the torque is too high.

• Use dust extraction system or mouth protection mask in dusty environments.

WARNING

Risk of Serious Injury or Death

Overspeed can result in serious injury or death.

• If a speed governor is used, make sure that the correct speed governor is assembled. Careless handling may put it out of order

• Do not disassemble security parts and always replace them if they are damaged.

• Always do a free speed check of the tool after service.

Change the grease in the angle gear after approximately 1000 hours of operation. See the directions under Lubrication.

Do an overhaul of the tool at six-months intervals. If it is in heavy duty service or not running correctly take it out of service more often for inspection.

Inspect the sealing lip and adjacent gear for wear. The seal is necessary to keep lubricant in the gear box.

Clean the strainer at the air inlet frequently to prevent clogging and decreased capacity.

Clean the motor parts and apply a thin layer of air lubrication oil onto the vanes and inner surface of cylinder and end plates.
Assemble the motor and do a check of that it is running free. Add two drops of oil through the air inlet and run the motor at idling speed for 5-10 seconds.

Replacement of vanes

Replace the vanes in the motor when a power drop of the tool is experienced. If the vanes are not replaced in time other motor parts may be damaged. For increased life length of the vanes use an oil lubricator to dose oil into the air inlet.

Lubrication instructions

• Rust protection and cleaning
• Lubrication guide
• Lubrication

Rust protection and cleaning

Water in the compressed air can cause rust. To prevent rust we strongly recommend to install an air dryer.

Water and particles can cause sticking of vanes and valves. This can be prevented by installing an air filter close to the product to avoid pressure drop.

Before longer standstills always protect your tool by adding a few drops of oil into the air inlet. Run the tool for 5–10 seconds and absorb any access oil at the air outlet in a cloth.

Lubrication guide

Lubrication

The tool is fitted with an angle gear which is lubricated with a fluid grease to ensure good wear resistance. To prevent overfilling, which could result in a rise in temperature and damage to seals, there is no lubrication nipple. Instead, the grease should be changed after approximately 1000 hours by removing the angle-gear spindle. Check every 500 running hours.

For accurate lubricating properties – use RHENUS LKR03 fluid type grease. For the requisite amount of grease, see table below.

Do not use ball bearing grease or chassis grease.
