Tempest VentMaster 576-HD Ventilation Fire Chain Saw
Tempest VentMaster 365-HD Ventilation Fire Chain Saw

The VentMaster 576-HD and 365-HD fire rescue chainsaws deliver the absolute best in cutting performance, built specifically for the fire service.

Sealed and Protected Carburetor/Air Filter
35 percent better engine cooling due to cover design in relation to cooling fan design. Air Filter cannot be crushed or lost. Tool-less compartment entry for easy access to spark plug, air filter, inspection and cleaning of cylinder cooling fins. Greatly reduces filter clogs.

Tool-Less "KIS-40" Depth Guage
Accurately control cutting depth, protect operator and safely speed cut. Fast, simple installation and removal, and eliminates the need to "roll the rafters".

VentMaster COBALT Guide Bar
Extremely hard COBALT alloy inserts at the wear points provide excellent wear, galling, and impact resistance. Retains these properties even at very high operating temperatures.

Centrifugal Force Air Cleaning System
Preliminary air intake cleaning rejects 97 percent of cutting residue and other airborne debris including drywall dust, concrete dust, smoke, water spray and more. Cleaner intake air means longer intervals between filter cleanings, longer runs at full power, less chain damage, smoother operation and reduced internal engine wear.

Raptor Carbide Chain
Engineered specifically to withstand the rigors of fire and rescue operations. Features an "open dual raker" design to protect the carbide cutters and control the depth of cut.
Tough and versatile enough to cut through:

• Plexiglass, Lexan & Hurricane Glass
• Tar and Asphalt Roofing Nails
• Light-Gauge Sheet Metal
• Wire-Reinforced Belting
• Trees and Green Wood

Plated Steel Splash Guard
Strong and durable to protect the saw during extreme cutting. Mounted with aviation-style star washers to prevent loosening due to vibration.

Angle Full Wrap Handle
Angled ergonomic handle allows safe operation in any position and protects saw from damage.

One Step Start/Stop
Combined Choke/Throttle Lock/Stop Switch eliminates flooding and allows fast, convenient starting and One Push positive stop, even with gloves.

"Smart Start" Decompression Valve
Valve reduces cylinder pressure for less starting resistance and easier starts.
