SAFETY PRECAUTIONS
Safety is everybody’s business and is based on your use of good common sense. All situations or circumstances
cannot always be predicted and covered by established rules. Therefore, use your past experience, watch out for
safety hazards and be cautious. Some general safety precautions are given below:
Failure to observe these notices could result in injury to or death of personnel.
DKeep fingers and clothing away from blower inlet and discharge ports,
revolving belts, sheaves, drive coupling, etc.

INTRODUCTION
YOUR KEY TO TROUBLE FREE SERVICE
Thank you for investing in Sutorbilt quality. The Sutor-
bilt reputation for rugged dependability has been
earned by over 50 years of service in demanding,
industrial operations where downtime cannot be
tolerated and efficient blower performance is expected.
Your Sutorbilt blower is a precision engineered blower
that has been carefully manufactured and thoroughly
tested at the state-of-the-art Gardner Denver Blower
Factory in Sedalia, Missouri.
As with other precision machinery, there are several
relatively simple installation, operation and mainte-
nance procedures that you must observe to assure
optimum blower performance. There is no guesswork
in the manufacture of your highly advanced Sutorbilt
blower and there must be none in preparing the blower
to get the job done in the field.
The purpose of this manual is to help you properly
install, operate and maintain your Sutorbilt blower. It is
essential that you review all sections of this manual in
preparation for installing your blower. Follow the
instructions carefully and you will be rewarded with
trouble--free Sutorbilt service ...yearinandyearout.

SECTION 1
EQUIPMENT CHECK
Before uncrating, check the packing slip carefully to be
sure all the parts have been received. All accessories
are listed as separate items on the packing slip, and
small important accessories such as relief valves can
be overlooked or lost. After every item on the packing
slip has been checked off, uncrate carefully. Register
a claim with the carrier for lost or damaged equipment.
Customers are cautioned to provide
adequate protection, warning and
safety equipment necessary to protect
personnel against hazards involved in
installation and operation of this
equipment in the system or facility.
STORAGE
Your Sutorbilt Blower was packaged at the factory with
adequate protection to permit normal storage for up to
six (6) months.
If the unit is to be stored under adverse conditions or
for extended periods of time, the following additional
measures should be taken to prevent damage.
1. Store the blower in a clean, dry, heated (if
possible) area.
2. Make certain inlet and discharge air ports are
tightly covered to prevent foreign material from
entering the air box.
3. All exposed, non--painted surfaces should be
protected against rust and corrosion.
4. Provide adequate protection to avoid accidental
mechanical damage.
5. In high humidity or corrosive environments, addi-
tional measures may be required to prevent rust-
ing of the blower internal surfaces.
6. To prevent rusting of gears, bearings, etc., the oil
reservoirs may be filled with normal operating oil.
Before running the blower, drain the
oil and replace to the proper operat-
ing level with clean, fresh lubricant.
7. Rotate the blower shaft (10 to 25 turns) monthly
during storage. Inspect the blower shaft (near the
shaft seal area) monthly and spray with rust inhibi-
tor if needed.
8. For long term storage (over six (6) months),
contact Sutorbilt Customer Service for recom-
mendations.
REMOVING PROTECTIVE MATERIALS
The shaft extension is protected with rust inhibitor
which can be removed with any standard solvent.
Follow the safety directions of the
solvent manufacturer.
Blower inlet and outlet are temporarily capped to keep
out dirt and other contaminants during shipment.
These covers must be removed before start--up.
The internal surfaces of all Sutorbilt units are mist
sprayed with a rust preventative to protect the machine
during shipment. Remove this film upon initial startup,
using any commercial safety solvent. Care should be
exercised to lock out the blower to prevent start--up
Rotating components will cause
severe injury in case of personal
contact. Keep hands away from blow-
er inlet and discharge ports.

SECTION 2
INSTALLATION
LOCATION
If possible, install the blower in a well lit, clean, dry place
with plenty of room for inspection and maintenance.
FOUNDATIONS
For permanent installations we recommend concrete
foundations be provided, and the equipment should be
grouted to the concrete. It is necessary that a suitable
base be used, such as a steel combination base under
blower and motor, or a separate sole plate under each.
Before grouting, equipment must be leveled, free of all
strains, and anchored so no movement will occur
during setting of grout. After grout has completely
hardened, a recheck is necessary to compensate for
shrinkage, etc. If required, add shims under blower feet
after final tightening of foundation anchor bolts to
remove strain from the blower housing.
Where jack screws or wedges are used during
grouting, they must be backed off or removed before
final tightening of anchor bolts.
Where a concrete foundation is not feasible, care must
be taken to insure that equipment is firmly anchored to
adequate structural members.
MOUNTING CONFIGURATIONS
The blower flex--mount design enables horizontal and
vertical mounting configurations with top or bottom
hand, right or left hand shaft positioning. The units are
center timed allowing rotation in either direction (refer
to FIGURE 1). If converting a blower from vertical to
horizontal, or horizontal to vertical mounting configura-
tion, additional mounting feet will be required.
REPOSITIONING THE MOUNTING FEET:
1. Position the mounting feet to the desired location
and snug the capscrew.
2. Place the blower on its feet on a flat surface.
3. Loosen mounting feet capscrews and level unit
up. The bench or blower base flatness should be
within .002 of an inch.
If the unit is not flat within .002 of an
inch, it will be necessary to shim the
blower feet at installation.
