the tubes for signs of wear and replace with new tubes as necessary. Realign the
pinch tube assembly with the grooves and securely tighten the thumb screws.
Monthly Requirements
Compressor Oil (Mach 5.0 PLUS only)
• •
The Mach 5.0 PLUS is equipped with a portable compressor that does not require
general maintenance, except adding oil. The compressor is equipped with a viewing
window with a minimum/maximum indicator line. If the oil is below the minimum
line, add oil as follows;
1. Ensure the unit power is off and the power cord is removed.
2. Open the access door on the right side of the unit.
3. Remove the oil fill bolt from the top of the compressor head.
4. Using the bottle of oil and extra tubing shipped in the accessory kit, install
the tubing to the top of the oil bottle to allow access to the oil fill hole.
Squeeze small amounts of oil at a time, allowing time to settle before
rechecking the level indicator. DO NOT OVERFILL.
5. Replace top bolt and ensure it is tight.
Oil overflow bottle (Mach 5.0 PLUS only)
•
Locate the clear oil overflow bottle at the bottom shelf of the Mach 5.0 PLUS unit.
Inspect the level of oil, and empty as necessary. Excess oil should be disposed of
as you would automobile motor oil.
Internal tubing
•
Inspect internal tubing for wear and air leakage. Listen for audible leaking sounds
and look for powder accumulation internal to the unit. Soapy water and a small
paint brush is ideal for finding small air leaks. If a powder leak occurs, inspect the
tubing going from the pinch valves to the exhaust bottle first, paying particular
attention to any “Y” fittings. If no damage is found, make sure the exhaust bottle is
empty, the exhaust bottle filter is clean and tight, and excess powder is cleaned from
the unit. Clean up excess powder to avoid contamination of other components and
to help isolate the leak area.
Handpiece Nozzles
•
Inspect all the handpiece nozzles for wear, paying close attention to the carbide insert
at the end of the tip. If there are any slits or chips, replace the nozzle. A worn
nozzle will greatly effect the performance of cutting and powder flow control. It is
possible to have a worn nozzle without any visible signs.
