In order to ensure that your Marschalk Compressor has a long service life and operates properly,
adhere to the cautions below and read this manual before use.
Read and understand the information contained in this manual and the included compressor
manufacturer's manual before operating unit.
This unit operates from a 12-volt DC power supply only. Do not operate in rain. Observe polarity
(Black Neg. /Red Pos.).
Compressed air can cause serious injury. Always direct air stream away from personnel. Wear eye
protection.
All compressors and engines generate heat under normal operating conditions. To avoid serious
burns, never touch the compressor head, exhaust parts, compressor relief valve, or engine muffler
during or immediately after operation.
Do not tamper with air compressor unit relief valve, as it has been preset at the factory and is not
adjustable.
Before use: Inspect all fittings and hoses for signs of damage, or loose fittings. With normal
operation some vibration will occur, which can cause fittings to come loose. Inspect and tighten as
necessary as part of a normal maintenance program and prior to each use of the unit. Never operate
a damaged unit.
Before transporting, servicing, cleaning or removal of any part, shut down compressor, remove
power, and relieve tank and hose pressure.
The air compressor provided with this unit is of the oil-less type, and as such, needs NO
lubrication/oil.
Always shut off air discharge ball valve at tank before attaching/detaching any air hoses or air
handling equipment.
Always remove power from unit before transporting or performing maintenance or servicing.
WARNING: TO AVOID THE RISK OF TANK FAILURE; DRAIN TANK FREQUENTLY DURING AND
AFTER EACH USE, TO MINIMIZE CONDENSATION BUILD-UP AND CORROSION INSIDE TANK.
WHEN DRAINING THE TANK, IF DEBRIS OR HEAVY RUST PARTICLES ARE DRAINED ALONG WITH
WATER, CONTACT MANUFACTURER FOR POSSIBLE TANK REPLACEMENT. IT IS RECOMMENDED
THAT TANK BE INSPECTED ANNUALLY AND REPLACED EVERY 3 YEARS.
