Features of VC85BS

Automatic priming is added to the highest capacity model of Tohatsu pump.

1. Light weight and compact
Engine and pump castings are made of anti-corrosive aluminum-alloy to reduce weight and prolong
working life. Compact unit in its class fits existing locker space, also can be carried by 2 firemen.

2. High pump performance
Both engine and pump are designed and developed specifically for fire-pump application by Tohatsu,
ensuring higher pump performance for its class.

3. Reliable engine with oil injection/auto mixing oil delivery system with optimal engine start-up
The engine of VC85BS is originally designed by Tohatsu for this model. Equipped with oil pump,
gasoline and engine oil are mixed automatically at a precise ratio to engine speed without mixing
fuel and oil by operator.

4. Automatic priming
Automatic priming is equipped as standard for VC85BS. On engine startup, the vacuum pump
automatically operates. When priming is not possible, a warning displays on the monitor.

   Prime 1meter in 4seconds (6m suction hose)
   Prime 3meter in 5.5seconds (6m suction hose)
   Prime 6meter in 8.0seconds (6m suction hose).

5. Centralized control
All gauges, throttle dial, control switches, and other warning lamps are grouped on the control
panel for easy operation.

6. Cooling water recirculation system
Engine cooling water is returned to the pump eliminating discharge outside of the pump, and
making surrounding area soaked.

7. Unique auto choke carburetor
This device helps engine start easier in all seasonal temperature conditions.

8. Engine overheat protection sensor
Overheat protection is provided on this model to safeguard the engine from cooling water loss,
and to protect engine when water is not discharging. This device stops the engine automatically
when engine temperature reaches 80℃.

9. Large capacity fuel tank
Integrated fuel tank with large capacity of 18liters ensures the fuel supply will last for 1 hour at
maximum throttle opening and load.

10. 90 degree rotating delivery outlets

11. Electric starter with back up recoil starter
An electric starter and back-up recoil starter are installed to guarantee starting engine under any

12. Maintenance free battery
Equipped with sealed type and maintenance free battery, once the battery is filled with a specified
electrolyte, maintenance of electrolyte is not required.

1. Battery charger
2. Floodlight projector
3. Plastic toolbox
