Frequently Asked Questions - 28357 Draper
How should I lubricate this pneumatic impact wrench?
Use pneumatic tool oil by adding 2-3 drops into the air inlet before each use. This keeps the internal components lubricated and prevents wear.
What air pressure should I use for optimal performance?
Set the air pressure to 6.3 bar (90 psi) at the tool inlet. Do not exceed this recommended pressure as it may cause damage.
What size air compressor is needed to run this tool?
A compressor with a minimum 3 HP motor and an air delivery of at least 4.5 cfm at 90 psi is recommended.
How do I adjust the torque on the impact wrench?
The torque is controlled by the regulator on the air pressure and the tool's throttle. Lower air pressure reduces torque, while higher pressure increases it.
Can I use this wrench to remove lug nuts from my car?
Yes, the high torque output and 1/2 inch drive make it suitable for lug nuts. However, always use impact-rated sockets and tighten lug nuts with a torque wrench.
What safety equipment should I wear while using this tool?
Wear safety goggles and hearing protection to protect against debris and high noise levels. Gloves are also recommended for a secure grip.
How can I prevent moisture damage inside the tool?
Use a water separator or air dryer in your air line to remove moisture. Additionally, drain the compressor tank regularly to prevent condensation.
What is the best way to store this impact wrench when not in use?
Store it in a clean, dry place away from moisture and extreme temperatures. Disconnect the air supply and keep the tool protected from dust.
Why doesn't my impact wrench start or run slowly?
Check the air supply pressure, ensure the trigger is fully depressed, and inspect for blockages in the air inlet or exhaust. Lubricate if the tool has not been used for a while.
Can this tool be used in cold weather conditions?
Yes, it can operate in temperatures as low as -10°C. In cold conditions, allow the tool to warm up for a few seconds before heavy use to avoid performance issues.
