the system pressure.
• Give compressor overall visual inspection and be
sure safety guards are in place.
• Check for any unusual noise or vibration.
Weekly
• Pull on the ring of the pressure relief valves to
make sure they are operating correctly. Air pres-
sure should escape when the ring is pulled. (Re-
fer to Fig. 11.)
• Check all pressurized components for rust, crack-
ing or leaking. Immediately discontinue use of
the equipment and relieve all system pressure if
any of these problems are discovered. Do not use
the equipment until it has been inspected and
repaired by a qualified mechanic.
• Clean the exterior surfaces of the compressor.
• Check the air filter and replace if necessary.
• Check system for air &/or lubricant leaks.
Monthly
• Check belt tension.
• Check flywheel retaining screws.
Every 6 Months (or every 500* hrs.)
• Change lubricant.
*Intervals may be extended to 1000 hrs. when Quin-
Cip lubricant is used. (Change more frequently in
harsher conditions.)
Lubrication
Before starting this compressor, check the lubricant
level. It should register between the high and low
level marks on the dipstick. Remove the dipstick to
add lubricant to the crankcase. Do not overfill.
Approximate Crankcase Lubricant Capacity
QTS-1 = 6.7 oz. (200 ml.) of Quin-Cip
QTS-3 = 12 oz. (354 ml.) of Quin-Cip
QTS-5 = 39 oz. (1150 ml.) of Quin-Cip
Quin-Cip lubricant has proven under extensive
testing to minimize friction and wear, limit lubricant
carryover, and reduce carbon and varnish deposits.
It will support the performance characteristics and
life designed into all Quincy compressors and is
highly recommended. Quin-Cip is available from
your local Quincy distributor in several container
sizes. Refer to the parts manual for part numbers.
A non-detergent SAE 10W, SAE 20W or SAE 30
weight lubricant may be used in your compressor.
Refer to the chart below to determine which viscosity
to use for your application.

Detergent lubricants are not recommended be-
cause they have a tendency to foam when used in
compressors.
Condensation
Rust can form inside the crankcase and on internal
components as a result of condensation. A compres-
sor must operate long enough during each run cycle
to reach full operating temperature in order to re-
duce the risk of condensation.
CAUTION!
Lubricant that appears milky on the dipstick may
have mixed with condensate. Failure to replace
contaminated lubricant will result in damage to the
compressor and may void warranty.
Condensation can also form in the air tank of your
compressor. When this happens, a mixture of air and
moisture will be expelled through the service valve
and into whatever is connected to the valve (e.g. air
hoses, metal air lines, pneumatic tools, spray guns).
An in-line filter or dryer, available from your local
Quincy distributor, may be required to eliminate the
moisture.
Condensation in the air tank can be kept to a
minimum by draining the tank on a daily basis. This
also reduces the risk of rust developing and weak-
ening the tank.
Belt Alignment & Adjustment
Drive belts tend to stretch with normal use and
require adjustment periodically (check monthly). In
order to adjust the drive belt the belt guard must be
removed. Prior to removing the belt guard, follow the
procedures outlined under MAINTENANCE.
