  Compressed air should be dry, air pressure should maintain 500kPa; Use clean soft water, in the last resort when using acid or alkaline water, inject some lubricating oil, turn off the water and no-load drill after the completion of the drilling process.

• 02

  Clean and reload the new air drill before using it, no-load drill after reloaded to check if it is normal. But no-load drilling process should under 2-3 mins.

• 03

  Clean pipe and routine maintenance and lubricate regularly make sure rock drill works in good condition.

• 04

  Inlet compressed air befor water, and should stop lnleting water first. Water pressure should be lower than compressed air pressure to prevent water from reflowing into rock drill cylinder.

• 05

  Adjust pressure valve when the steel rotary mechanism moving slowly, shutdown YT29A rock drill if steel rotary mechanism stop moving and invalid after reducing air-leg axial trust.

• 06

  Wipe couplings clean and connect hydraulic hoses to an unpowered (not activated) hydraulic source.

• 07

  Remove the tool steel. With a clean object, push the piston through the bushing to it's inner most position. Remove the object and using the grease nipple located in the nose assembly, lubricate the bushing

  Failure to grease the nose assembly every 8 hours of operation will cause the drive system to stop rotating.

• 09

  Clean off any accumulation of particles from beneath the trigger area. Spray with a light oil and wipe off excess.
