Toxic exhaust fumes -

 The unit produces toxic exhaust fumes when the engine is 

running. These gases (carbon monoxide) may be colourless and odourless. To reduce 

the risk of serious or fatal injury from breathing toxic fumes, never run the unit 

indoors or in poorly ventilated locations.

9.  

Moving parts - 

This unit has a rotating impeller. Never perform any maintenance or 

assembly on this unit while the engine is running. Keep hands and feet away from 

moving parts. Keep guards in place and in proper working order.

10.  

Wear personal protective equipment -

 When using this tool, wear safety glasses with 

side shields or goggles to provide necessary eye protection. Wear ear protection to 

prevent hearing damage. Use a face or dust mask if the work environment is dusty.

11.  

Do not force the tool -

 It will perform better with less likelihood of personal or 

mechanical injury if it is used at the rate for which it is designed.

12.  

Store idle tool indoors -

 When not in use, the chainsaw should be stored indoors in a 

dry and high or locked-up place out of the reach of children.

13.  

Maintain the chainsaw with care -

 Keep the chainsaw clean for optimal performance 

and to reduce the risk of injury. Keep the handles dry, clean, and free from oil and 

grease. Follow the additional recommendations described in the maintenance 

section of this manual.

14.  

Use care -

 Do not direct the unit stream toward people or animals. Watch out for 

children, pets, open windows and blow debris safely away.

15.  

Use the right tool -

 Do not use the tool for any job except that for which it is 

intended.

16.  

Avoid dangerous environments -

 Do not use the chainsaw in rain, damp, or wet 

locations.

17.  

Stay alert -

 Watch what you are doing. Use common sense. Do not operate the 

chainsaw when you are tired or under the influence of drugs, alcohol, or other 

medication.

CHAIN SAW USE AND CARE

Do not force the chainsaw. Use the correct chainsaw for your application. The correct 

chainsaw will do the job better and safer at the rate for which it was designed.

Do not use the chainsaw if the switch does not turn it on and off. Any chainsaw that 

cannot be controlled with the switch is dangerous and must be repaired.
Store idle chainsaws out of the reach of children and do not allow persons unfamiliar 

with the chainsaw or these instructions to operate the chainsaw. Chainsaws are 

dangerous in the hands of untrained users.

Maintain chainsaws. Check for misalignment or binding of moving parts, breakage of 

parts and any other condition that may affect the chainsaw's operation. If damaged, 

have the chainsaw repaired before use. Many accidents are caused by poorly maintained 

chainsaws.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting 

edges are less likely to bind and are easier to control.

Use the chainsaw, accessories and tool bits etc. in accordance with these instructions, 

taking into account the working conditions and the work to be performed. Use of the
