Fuel Safety (Refueling/Fuel mixture/Storage)

Never refuel the CE807R-B¹ Rotary saw while the engine is running. Make sure there is plenty of ventilation when refueling or mixing fuel (gasoline and 2-cycle oil) Move the CE807R-B¹ Rotary saw at least 10 ft (3m) from the refueling point before starting it.  

Never start the CE807R-B¹ ROTARY Saw.......

-If you have spilled fuel on it. Wipe off the spillage and allow remaining fuel to evaporate

-If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water.

-If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.

Store and transport the CE807R-B¹ Rotary saw and fuel so that there is no risk of leakage or fumes coming in contact with spark or open flames, for example, from electrical machinery, electric motors, electrical relays/switches or boilers.

Always store fuel in an approved container designed for that purpose.

When storing the CE807R-B¹ Rotary saw for long periods the fuel tank should be emptied. Contact your local gas station to find out where to dispose of excess fuel.

BASIC SAFETY RULES

Look around you:

To ensure that people, animals or objects cannot affect your control of the CE807R-B¹ Rotary saw. To make sure that none of the above come into contact with the cutting blade. 

Use extreme caution when using the CE807R-B¹ Rotary saw in bad weather, such as dense fog rain, strong wind, intense cold, etc. Working in bad weather is tiring and can lead to dangerous conditions, i.e., slippery surfaces.

Never start to work with the CE807R-B¹ Rotary saw before the working area is clear and you have a firm foothold. Look out for any obstacles with unexpected movement. Ensure when cutting that no material can become loose and fall, causing operator injury. Use caution when working on sloping ground.

Make sure that clothing and parts of the body stay clear of the cutting equipment when it is rotating.

Maintain a safe distance from the cutting equipment when it is rotating.

The guard for the cutting equipment must always be on when the machine is running.

Ensure that the working area is sufficiently illuminated to create a safe working environment.

Do not move the CE807R-B¹ Rotary saw when the cutting equipment is rotating.

Always ensure you have a safe and stable working position.

Make sure that no pipes or electrical cables are routed in the area to be cut.

Ask yourself...”IS WHAT I’M ABOUT TO DO SAFE?”

WARNING! Take care when handling fuel. Keep in mind, the risk of fire, explosion and

inhaling fumes.

WARNING! This section describes basic safety directions for using a CE807 Rotary Rescue Saw. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your dealer, service agent or an experienced rescue saw user. DO NOT attempt any task that you feel unsure of!

(Check wires for damage or wear) g)Remove the cutter arm. (Refer to Removing and Inspecting the belt section)

4. Clean the powerhead and cooling fins with solvent. A putty knife or similar tool may be used to remove stubborn debris. NOTE: Do not allow solvent to enter the carburetor or muffler when cleaning.
