MAINTENANCE (CONTINUED)
Valve Spool Assembly Maintenance
 Send into authorized repair center for service.
Trigger Maintenance Procedure
 Inspect trigger pin valve by insuring 35 has not come loose. The proper depth should be just
under the valve stem.
 If adjustment is necessary using a fork wrench or tire valve tool, screw the trigger pin 34 into
the valve stem. A very small amount of loctite243 is ok around the threaded portion only.
 If the trigger still fails, remove the trigger pin assembly from the valve stem and inspect the
seal around the trigger pin for damage. If damaged, purchase a replacement part. Re-
assemble according to the previous step.
PREVENTIVE MAINTENANCE
In order to maintain the tool in a safe working order it is important to carry out regular maintenance
as prescribed by the manufacturer. A thorough inspection replacement of all seals within the tool
should be carried out after 500,000 actuations or annually, whichever is the sooner. Seal Life is
dependent on the size of the rivet applied, the frequency of use in one minute, the cleanliness of the
tool, proper maintenance within the time interval suggested and total number of actuations. The
seal life is a limited warranty item and should only be replaced by trained personnel. Item numbers
in parentheses refer to assembly drawing part numbers
Daily
 Check for air leaks. Any damaged hoses should be replaced
 Lubricate the tool by pouring a 1 drop of the enclosed lubricating oil into the air inlet on the tool
 If there is no pressure regulator, bleed the airline to clear it of accumulated dirt or water before
connecting the air hose to the tool. If there is a filter, drain it.
 Check for proper nose piece use depending on the size of the rivet.
 Remove front jaw nose assembly and clean all visible areas beneath the Nose Cap (3) with an air hose
to remove metal shavings and debris. Remove jaw housing as necessary and consumable parts
thoroughly with mineral spirits. Inspect for cracks or other damage to jaw or nose area. Replace if
necessary.
 Insure that rotary valve for the vacuum on the mandrel collection unit is correctly adjusted for fastener
retention
Weekly
 Carry out procedures as per daily maintenance instructions above
 Clean and inspect the jaws for signs of damage or wear (groove running through the jaw serrations).
Follow the instructions on page 4 for cleaning of jaws. Reassemble the tail jaws with a light coating of
red grease on the outer face that contacts the jaw housing. Do not allow grease to contaminate the
grooved inner face of the jaws as mandrel slippage may result.
Monthly
 Carry out procedures as per weekly maintenance instructions above
 Check and replace cylinder bodies if there are signs of damage or cracks.
Semi-Annually
 Carry out procedures as per monthly maintenance instructions above
 Check that the stroke is greater than 1.0”. If less, follow bleeding procedure.
 Depending on the frequency of use, further maintenance may be required to replace the hydraulic seals.
