Why does my Ingersoll-Rand MX90 Power Tool paving breaker lack power?
- S
  Sherry CollinsAug 12, 2025
  Your Ingersoll-Rand Power Tool paving breaker may lack power due to several reasons. It could be due to low air supply pressure; the air supply pressure at the tool should be 90 to 100 psi (6.2 to 6.9 bar). Another reason could be running on fronthead cushion, so keep shank fed-up to the work and always maintain a constant pressure when operating the breaker. Also, check for plugged air passages by dismantling the breaker and cleaning out all ports and passages. Lack of lubricating oil or a sticking valve could also be the cause. Maintain the proper oil level in the lubricating oil reservoir, ensuring the steel shank shows a film of oil. Clean the valve chest parts if the valve is sticking, and never use dirty oil or oil that does not conform to the recommended specifications.

  If your Ingersoll-Rand Power Tool paving breaker is overheating after the break-in period, it could be due to several reasons. You might be running on the fronthead cushion, so ensure you keep the shank fed-up to the work and maintain constant pressure. Another cause could be the piston not hitting the shank because of a short shank; remove the shank piece from the breaker. Pulling steel at full throttle can also cause overheating, so always use minimum throttle when pulling steels. Finally, a lack of lubrication or improper lubricating oil could be the issue. Ensure the lubricating oil reservoir is full of proper lubricant before operating the breaker.

Why does my Ingersoll-Rand MX90 paving breaker lose power rapidly?
- D
  Daniel ZavalaAug 23, 2025
  Your Ingersoll-Rand Power Tool paving breaker may be losing power rapidly due to a restriction in the air supply line. Never allow the air supply to kink or make sharp bends. Also, the air supply line might be too long; as a general rule, keep the air supply line under 50 ft. (15 m). The diameter of the air supply line might also be too small; a 3/4 in. (19.1 mm) diameter air supply is recommended for the breaker.

Why is my Ingersoll-Rand Power Tool operating erratically or sluggishly?
- A
  Amy WestAug 27, 2025
  Erratic or sluggish operation of your Ingersoll-Rand Power Tool may be due to lubricating oil that is too heavy, slowing down valve action. Use only the recommended lubricating oil. Another cause could be gummed oil or dirt in operating parts. Dismantle the breaker and clean out dirt and gummy residue, then service the breaker with clean oil. Protect the tool from dirt when idle.

How to prevent freezing at the exhaust ports of my Ingersoll-Rand Power Tool?
- T
  turnerjohnAug 31, 2025
  Freezing at the exhaust ports of your Ingersoll-Rand Power Tool can be prevented by addressing excessive moisture in the air supply line. Install moisture traps in the air supply line or add anti-freeze lubricant directly through the air inlet. Use 'KILFROST' anti-freeze lubricant or equivalent.

What causes fogging in my Ingersoll-Rand MX90 Power Tool, and how can I fix it?
- N
  nmillerSep 3, 2025
  Fogging in your Ingersoll-Rand Power Tool can be caused by excessive moisture in the air supply line. Blow out air lines, and if moisture traps are installed, drain the moisture. Another cause is over lubrication. Clean the lubricating oil reservoir and adjust for the proper rate of feed.

What should I do if the piston seat on my new Ingersoll-Rand Power Tool machine is overheating?
- J
  Jessica LeeSep 7, 2025
  If the piston seat on your new Ingersoll-Rand Power Tool machine is overheating, it is likely because the breaker is not properly broken in. Stop operating the breaker and perform initial servicing. Never run a new breaker at full throttle until a proper break-in period has been completed.
