ABOUT TEMPEST
Tempest Technology Corporation is the leading manufacturer
of products and accessories for environmental management in
reghting and industrial applications.
Tempest began as a manufacturer of gasoline and electric powered
blowers for the re service. ese departments use the Tempe st
Power BlowerTM to provide “Positive Pressure Ventilation / Attack”
(PPV/PPA) to remove heat, gases and smoke from the interior of
a burning structure.
Tempest has expanded into other industries and found new
applications for its products. e Tempest Power BlowerTM and
PPV/PPA are used by industrial applications to control dust, fumes
and unhealthy gases like carbon monoxide, greatly improving
safety in conned spaces.
Tempest Technology Corporation has earned a reputation as a
leader and innovator in the air movement industry and continues
in that role today.

SAFETY GUIDE
Failure to follow the operating, maintenance and lubrication
requirements set forth in this manual may result in serious
personal injury or death and/or damage to equipment or property.
e following WARNING statements indicate potentially
hazardous conditions for operators and equipment. Make certain
that anyone who works on or around this tool has read and fully
understands the safety precautions listed.
1. Carefully read this owner’s manual and the power head
manufacturer’s manual before attempting to operate, service
or disassemble any part of your VentMaster® Fire Rescue Saw.
2. DO NOT operate the unit when mentally or physically
fatigued or impaired.
3. Stay away from rotating parts; avoid wearing loose jackets,
shirts, and ties. Keep hands and feet away from moving parts.
4. Keep all unauthorized personnel at a safe distance from the
saw.
5. Keep all guards in place. DO NOT make repairs while the
unit is running. DO NOT operate if any guard is not in place.
6. Always wear eye protection. Loose debris can be picked up
and own in the air.
7. Hearing protection is required. Engine and cutting noise may
exceed safe dB levels.
8. Gasoline is extremely ammable and is explosive under
certain conditions. To prevent re hazards, do not place
ammable objects close to the engine.
9. Do not overll the fuel tank. Aer refueling, make sure the
tank cap is closed properly and secured. If any fuel is spilled,
make sure the area is dry before starting the engine.
10. Never operate in an enclosed or conned area over prolonged
periods of time. Exhaust contains poisonous carbon
monoxide gas; exposure may cause loss of consciousness and
may lead to death.
11. e muer becomes very hot during operation and remains
hot for some time aer stopping the engine. Be careful not
to touch the muer while it is hot. To avoid severe burns or
re hazards, let the engine cool before transporting or storing
the unit.
12. It is the sole responsibility of the owner/operator to develop
procedures for proper use of the VentMaster® Fire Rescue Saw
in accordance with generally accepted ventilation techniques
as well as the organization’s own operating procedures, before
placing the unit into service.

VENTMASTER® FIRE RESCUE CHAINSAW DATA
OPERATING PROCEDURES
PRE-OPERATION
VISUAL INSPECTION
Aer receiving and unpacking your saw, be sure to carefully
inspect it for any damage that might have occurred during
shipping. Should you nd any damage: PLEASE NOTIFY
TEMPEST TECHNOLOGY CORP. IMMEDIATELY AT
+1 559.277.7577.
CHAIN TENSION
Always ensure the saw’s chain is tensioned properly before
operation. To tension the chain, follow the directions below.
1. Shut o the engine, set upright and let the chain cool down.
2. Loosen the stud nuts that hold the guide bar onto the
engine.
3. While holding the bar tip UP, adjust the chain tension
screw to the position that allows the (cold) chain to pass
freely around the bar.
NOTE: e chain should NOT hang down more than 1/8”
below the bottom rail of the guidebar.
4. While holding the bar tip UP, tighten the nuts on the studs.
5. Before starting the saw, check the chain tension once again.
If it is not correct, loosen the nuts and repeat the above.
Proper tension will extend the life of the chain and enhance its
cutting performance.
LUBRICATION
Chainsaws require bar and chain lubrication during operation.
Always ensure the correct amount and type of oil is used before
starting your VentMaster® Fire Rescue Saw. Please see engine
manufacturer’s manual for details on proper lubrication.
OPERATION
CHAIN SPEED
It is important to run saw at FULL THROTTLE when entering the
cut, during the cut and exiting the cut (Release throttle only aer
full exit from cut).
FORCING THE CUT
Always let the chain do the work. Do not put extreme pressure on
chain while cutting. Excessive pressure causes the chain to slow
down and can cause carbide tip failure also causing heat damage
to the bar. Slow cutting could indicate chain needs sharpening.
SHEET METAL AND FIBER GLASS
Always use the KIS-40 depth gauge when cutting thin materials
such as sheet metal, aluminum siding or berglass. e depth
gauge can be set to expose 1/4” to 1/2” of the tip of bar and chain
for cutting these materials. ese thin materials will shake and
vibrate when the bar and chain are inserted too deep and can
cause carbide tip failure.
MAINTENANCE
Keepenginecleanandtunedproperlypertheenginemanufacturer’s
specications to maintain maximum engine speed/performance.
Elements such as a dirty air lter can cause gradual power loss
which can result in carbide chain tip failure.
NOTE: All models listed come equipped with the Raptor Carbide Chain (0.404 Pitch, 0.063 Gauge).

RAPTOR CARBIDE CHAIN CARE
While carbide chains are extremely durable, improper use and
poor saw maintenance can cause chain damage and failure.
During operation, the chain will heat up and loosen on the bar.
is is normal. Aer cooling, the chain will return to its original
size. Chain stretch will continue throughout the chain’s life. To
ensure optimum chain life and performance, always ensure proper
chain tension is set prior to use. To set the chain’s tension, see the
directions under Operating Procedures, Pre-Operation.
NEW CHAIN BREAK-IN
When breaking in a new chain, run at low speed for two (2)
minutes. Ensure that there is adequate oil lubrication to the bar
and chain. Stop the engine and check chain tension again. If the
chain has loosened, tighten it to the correct tension. Check aer a
few easy cuts and readjust if nececssary. To set the chain’s tension,
see the appropriate directions under Operating Procedures, Pre-
Operation.
NOTE: e drive sprocket should be changed every time a
new chain is put on a saw.
SHARPENING
• e Raptor carbide chain is ground at an angle of 29 degrees
with 15 degrees on the vertical.
• Depth gauge settings: 25 to 30 thousandths of an inch. When
the depth gauge is led more than 30 thousandths of an inch,
it increases the possibility for the carbide tip to break o.
• As a general rule, the depth gauges should be led with each
sharpening of the chain using a at le and depth gauge tool.
• Carbide chain sharpening requires the use of specialized
diamond-abrasive tools. “Flat facing” is done using a 1FF1
style diamond wheel. “Round facing” is done using an EZE-
Lap diamond or a contoured diamond wheel.
CHAIN REPAIR
Inspect chain aer each use. When a chain has more than ve
cutters missing or heavily damaged, it is recommended the
chain be taken out of service for repair. If two or more cutters in
succession are missing or are damaged, the chain should be taken
out of service for repair. Considerable damage could occur to the
remaining cutters if chain is used.
Cutter replacement depends on overall condition of the rest of the
cutters to determine if the chain should be repaired or replaced.
As a general rule, if ve or more cutters are missing or damaged it
is more cost eective to replace the chain.
e drive sprocket should be changed every time a new chain is
put on a saw. e cutting performance is diminished when a worn
drive sprocket has a loose t, causing “play” as the drive links of a
new chain are pulled through. is can put premature wear on a
new chain, causing product failure.
Tempest oers complimentary chain evaluation and optional chain
repair/sharpening. Contact customer service at 800.346.2143 with
questions regarding chain repair service.
