CALIFORNIA PROPOSITION 65
This product or its power cord may
contain chemicals known to the
State of California to cause cancer and birth defects or
other reproduc ve harm. Wash hands a .gnildnahre
1. Allow only trained, authorized persons who
have read and understood these opera ng
instruc ons to use this compressor. Failure
to follow the instruc ons, procedures and
safety precau ons in this manual can result
in accidents and injuries.
2. NEVER start or operate the compressor under
unsafe condi ons. Tag the compressor,
disconnect and lock out all power to it to
prevent accidental start-up un the condi-
on is corrected.
3. Install, use and operate the compressor only
in full compliance with all per nent OSHA
regula ons and all applicable Federal, State
alugerdnasdradnats,sedoClacoL& ons.
4. NEVER modify the compressor and/or controls
in any way.
5. Keep a rst aid kit in a convenient place.
Seek medical assistance promptly in case
of injury. Avoid infec n by caring for any
small cuts and burns promptly.
Breathable Air
1. NEVER use air from this compressor for
breathable air except in full compliance with
OSHA Standards 29 CFR 1910 and any other
Federal, State or Local codes or regula ons.
Death or serious injury can result
from inhaling compressed air
without using proper safety
equipment. See OSHA standards
on safety equipment.
2. DO NOT use air line an -icer systems in air
lines supplying respirators or other equip-
ment used to produce breathable air. DO NOT
discharge air from these systems in unven -
lated or other con ned areas.
Pressurized Components
This equipment is supplied with a ASME designed
pressure vessel protected by an ASME rated relief
valve. Pull the ring before each use to make sure
the valve is func onal. Refer to gure 12. DO
NOT a empt to open valve while the machine is
under pressure.
Personal Protec ve Equipment
Be sure all operators and others around the
compressor and its controls comply with all appli-
cable OSHA, Federal, State and Local regula ons,
codes and standards rela ng to personal protec-
ve equipment. This includes respiratory protec-
ve equipment, protec on for the extremi es,
protec ve clothing, protec ve shields and barri-
ers, electrical protec lanosrepdnatnempiuqeev
hearing protec ve equipment.
Inspec on
Inspect compressor prior to any
use. Check for external damage
that might have occurred during
transit. Be careful of movingparts
then test pulley by turning it
freely by hand. Report any dam-
age to deliv .yletaidemmireirracyre
Make sure pallet-mounted
compressors are firmly secured to
the pallet before moving. NEVER a mpt to move
a compressor that is not secure as serious injury or
property damage could occur.
A forkli may be necessary for unloading the
Flexzilla compressor. Use all forkli safety measures
and require a cer ed forkli operator. Refer to re

Warranty only valid by following conditions expressed in the Warranty Statement section of this Air Compressor Manual.

Forkli Safety
1. Make sure li operator stays aware while
moving compressor.
2. Be sure load is secure and well balanced
before moving the compressor.
3. Make sure forks are fully engaged and level
before li ing or moving compressor.
4. Keep load as low as possible and observe
safe opera ng prac ces.
Figure 1: Keep unit level
Li ing Safety
1. Carefully inspect all li ing equipment and make
sure it is in good condi on. Rated capacity should
exceed compressor weight. Make sure li ing hook
has a func onal safety latch or equivalent and is
properly a ched to li ing feature.
2. Make sure li ing points are in good condi on and
hten any loose nuts or bolts before li ing.
3. Use provided li ing feature or appropriate sling. A
sling must be used when moving compressor with a
helicopter or other air-borne equipment. Be sure to
follow OSHA standards 29 CFR 1910 Subpart N.
4. Use guide ropes or equivalent toprevent twis ng
or swinging of the compressor while it is in the
air and NEVER a empt to li in high winds. Keep
compressor as low to the ground as possible.
5. Keep persons away and makesure noone is under
the compressor while it is li ed.
6. Only use li ing features provided for en com-
pressorpackage.NEVERuseboltsorotherhookson
invididual components to move the compressor.
7. Makesure to put compressor on a level surface that
can support the weight of the compressor and load-
ing equipment.
Do not operate unit if damaged
.esurognildnah,gnippihsgnirud
Damage may result in burs ng and cause injury or
property damage.
Installa on
Area
1. Install compressor in a clean, dry and well-lit
area. Be sure installa niatniamnacaerano
a temperature range between 35 - 110 F.
Ifambient temperature drops
below 32 F, be sure to protect
safety/relief valves and drain valves from freezing.
NEVER operate compressor with temperatures
below 15 521evobaroF F.
2. Allow su cient space around compressor for
maintenance access and adequate air ow.
Mount unit with pulley towards wall and
leave a minimum of 15 inches of clearance.
3. Use shims to level compressor if installa on
area is not at. This will avoid excessive
vibra on and premature pump wear.
DO NOT install compressor in boiler
room, paint spray room or area
where sandblas ng occurs. Make
sure inlet air is away from exhaust
fumes or other toxic, noxious or
corrosive fumes or substances.
4. If acid is used in opera riarotnemnorivnegn
is dust laden, pipe intake to outside, fresh air.
Increase pipe size by one size for every 20 feet
of run. Be sure to install protec ve hood around
intake lter.
5. In opera ng environments where excessive wa-
ter, oil, dirt, acid or alkaline fumes are present,
sirotom)delooc-naf,desolcneyllatot(CFETa
recommended. Check nameplate for motor type.
6. Insulate coldwater or other low temperature
pipes that pass overhead to avoid condensa on
dripping on compressor which could cause rust
and/or motor shor ng.
Piping
Safety Steps
1. Install appropriate ow-limi ng valves as nec-
essary according to pipe size(s) used and run
lengths. This will reduce pressure in case of hose
failure, per OSHA Standard 29 CFR 1926.302(b)(7).
2. Flow-limi ng valves are listed by pipe size and
rated CFM. Select appropriate valves accordingly,
in accordance with the manufacturer’s recommen-
da ons.

7. For permanent installa ons of compressed
air systems, determine total length of sys-
tem and select correct pipe size. Make sure
underground lines are buried below frost line
and avoid areas where condensa on could
build up and freeze.
8.
Test en re piping system before underground
lines are buried. Be sure to nd and repair
all leaks before using compressor.
Never exceed recommended pressure
or speed while opera ng compressor.

Start-Up
1. This unit is shipped with pump break-in oil
and should be ready to operate. Be sure to
check for proper oil level before opera ng
the compressor. Oil should be in center of
site glass. See gure 8.
Use only Flexzilla Compressor Oil.
Use of any other product will
cause product damage and void

be 1/2 inch slack. Refer to maintenance sec-
on if adjustment is necessary.
Always make sure main power is
o before touching belts or other
moving parts of compressor.
3. Lightly push power switch to make sure sys-
tem is working.
4. If motor sha is not turning counter clock-
wise, disconnect power to terminal block

absence is necessary.
Compressor components can
become hot during opera on.
Avoid bodily contact with hot
liquids, hot surfaces and sharp
edges and corners.
Belt Adjustment
Be sure to relieve all system
pressure, then lock out power and
tag compressor to prevent
unexpected movement of the unit.
Inspect belt tension a er rst 30 hours of opera on
