Maintenance Instructions - Matco Tools MT3800 Manual

DISASSEMBLY:
10mm
Note: Reverse threads
Use the provided wrenches or a 10mm and 8mm wrench to loosen
the mandrel from the tool by turning it clock-wise due to the
reverse threads.
ADJUSTMENT:
#21 Cap
Nut/Wheel
Adjustment of the stroke may be necessary at times based on the
user's application, however make sure the #10 Lock Nut is adjusted
enough forward (and not too far back) so that the #4 Connector
Housing relieves enough spring pressure when installed to allow
the #21 Cap Nut/Wheel to freely spin.
If the rear spinning wheel does not spin freely,
adjust the #10 lock nut and #7 Spindle Guide until it does move
freely with the #4 Connector Housing installed.

NOSE NUT:
Install the #2 Nose Nut on each new nosepiece to be used. Adjust
to lock the nosepiece in place closer or further away as needed.
The further away from the tool the nosepiece is locked into place,
the more the stroke will be applied to the rivet nut and/or the less
the rivet nut can be threaded onto the mandrel.
DO NOT OVER SET RIVET NUTS, ONLY ADJUST NOSEPIECES
FORWARD AND INCREASE AIR PRESSURE AT REGULATOR AS
NEEDED. OVER SETTING RIVET NUTS CAN CAUSE DAMAGE TO
YOUR WORKPIECE AND/OR THIS TOOL.

MAINTENANCE INSTRUCTIONS:

1.) LUBRICATION:
Before connection of the hose, apply 4 to 5 drops of a good
quality air tool oil at the air inlet. After 3 to 4 hours of operation,
oiling may be necessary again.
2.) TIGHTNESS OF PARTS:
Regularly check whether all connection parts are fastened
securely. Follow this procedure daily before beginning work.
3.) STORAGE:
Avoid storing the tool in a location subject to high humidity.
If the tool is left unused, the residual moisture inside the tool
can cause rust. Before storing and after operation, oil the
tool at the air inlet with a good quality air tool oil and run it
for a short period.
4.) DISPOSAL:
Follow national legislation of waste disposal.
5.) ORDERING REPLACEMENT PARTS:
For further operational and handling information or for
replacement of parts and components, contact the sales agent
from whom you purchased the tool or the service division of
our company.
*When ordering parts and components, give each part number,
name, and quantities.
