TROUBLE SHOOTING HYDRAULIC TORQUE WRENCH
Tool failure, although rare, does occur. Such failure is most often in the hydraulic couplers or hoses. These
items are repairable or replaceable immediately, since they are available universally. Failures of structural
members of the tool are quite rare, however, replacement parts are available from stock. All repairs to Atlas
Copco tools may be made by reasonably experienced individuals according to the aforementioned instructions.
Otherwise, please contact Atlas Copco to schedule a quick repair of the tool.
Lubrication: All moving parts should periodically be coated with a good quality lubricant as Molykote with
Graphite P37 or Dow Corning 1000. Under harsh environmental conditions, cleaning and lubricating
should be performed more frequently. Warning: Sea Water is very corrosive, and, therefore, tools exposed
to sea water should be maintained more frequently.
Hydraulic hoses: Hoses should be checked for cracks and leaks after each job. Hydraulic fittings can
become plugged with dirt and should be flushed periodically. Hydraulic hoses have to wear a valid control
certification.
Quick-Connects: Fittings should be kept clean and not allowed to be dragged along the ground or floor,
as even small particles of dirt can cause the internal valves to malfunction.
Springs: Springs are used for the drive pawl assembly and for the accuracy assurance pawl. These
springs can be replaced if necessary.
Cylinder Seals: If the cylinder requires disassembly, it is recommended that the cylinder seals be replaced
at the same time. Seal kits are readily available.
Structural Member: All structural parts on the tool should be inspected once a year to determine if there
are any cracks, chips or deformities. If so, immediate replacement is required.
Recommended Service intervals are:
1. Heavy Duty use or use in corrosive/harsh environments – every 3 Months
Internal Drive components may require frequent inspection and re-lubrication under heavy duty
cycles, e.g. weekly
2. Normal use – every 6 months
3. Light or infrequent use – every 12 months

TROUBLESHOOTING POWERPACKS
Atlas Copco Hydraulic Power Packs are precision-built units and, as such, do require a certain amount of care
and maintenance
Hydraulic Oil should be completely changed after every 40 hours of operation, or at least twice a year.
Always make sure the reservoir is filled with fluid. If additional oil is required, use only high- grade hydraulic
oil such as grade 46.
Quick-Disconnect Fittings should be checked periodically for leaks. Dirt or foreign materials should be
kept away from fittings. Clean before use.
Hydraulic Gauge: Some gauges are liquid filled. Should this liquid level drop, it indicates external leakage,
and replacement is necessary. Should the gauge fill with hydraulic oil, it indicates internal failure and it
should be discarded.
Filter on Pump: The filter should be replaced twice a year in normal use and more often if the pump is
used daily or in a dirty, harsh environment.
Remote Control: (Air Unit) The airline to the remote control unit should be checked for obstructions or
kinks in the line periodically. If there is a bend or break in the line, it must be replaced. The spring- loaded
buttons on the remote handle should be checked in the event of operating difficulties. (Electric Unit) The
switch buttons should be checked periodically if any indications of problems exist.
Air Valve: This valve should be checked twice a year.
Armature: (Electric Unit) Check yearly.
Pumping unit: The pump should be overhauled every 2 years. This can be done by Atlas Copco or by a
qualified hydraulic service centre.
