It is vital that you read and understand 
this user manual before using the product, 
including safety warnings, and any 
assembly and operating instructions. 
Keep the manual for future reference. 

Safety precautions and recommendations 
detailed here must be fully understood 
and followed to reduce the risk of injury, 
fire, explosion, electrical hazard, and/or 
property damage. 

Safety information presented here is 
generic in nature 

– some advice may not 

be applicable to every product. The term 
"equipment" refers to the product, be it 
electrical mains powered, battery powered 
or combustion engine powered. 

 

Before Use

 - If you are not familiar with 

the safe operation/handling of the 
equipment, or are in any way unsure of 
any aspect of suitability or correct use 
for your application, you should 
complete training conducted by a 
person or organization qualified in safe 
use and operation of this equipment, 
including fuel/electrical handling and 
safety. 

  Do NOT operate the equipment in 

flammable or explosive environments, 
such as in the presence of flammable 
liquids, gases or dust. The equipment 
may create sparks or heat that may 
ignite flammable substances. 

  Keep clear of moving parts. 

  Equipment may be a potential source of 

electric shock or injury if misused. 

  Do NOT operate the equipment if it is 

damaged, malfunctioning or is in an 
excessively worn state.  

  Do NOT allow others to use the 

equipment unless they have read this 
manual and are adequately trained.

operating range of the equipment or the 
general work area. 

  If devices are provided for connecting 

dust extraction / collection facilities, 
ensure these are connected and used 
properly. Dust collection can reduce 
dust-related hazards. 

General Personal Safety 

  Wear appropriate protective equipment 

when operating, servicing, or when in 
the operating area of the equipment to 
help protect from eye and ear injury, 
poisoning, burns, cutting and crush 
injuries. Protective equipment such as 
safety goggles, respirators, non-slip 
safety footwear, hard hat, hearing 
protection etc should be used for 
appropriate equipment / conditions.

gets on your clothing, change clothing. 

  Do NOT smoke near fuel or when 

refuelling. 

  Always shut off the engine before 

refuelling. 

  Do NOT refuel a hot engine. 

  Open the fuel cap carefully to allow any 

pressure build-up in the tank to release 
slowly.

  Always check for fuel leakage. If fuel 

leakage is found, do not start or run the 
engine until all leaks are fixed. 

General Carbon-Monoxide Safety

 

  Using a combustion engine indoors 

CAN KILL IN MINUTES

. Engine 

exhaust contains carbon-monoxide 

– a 

poison you cannot smell or see. 

  Use combustion engines OUTSIDE

any other condition that may affect its 
operation. If damaged, have the 
equipment repaired by an authorised 
service centre or technician before use. 

  Prevent unintentional starting of the 

equipment - ensure equipment and

items that are not a part of the 
equipment from it before starting or 
switching on. 

  Do not force the equipment. Use the 

correct equipment for your application. 
Equipment will perform better and be 
safer when used within its design and 
usage parameters. 

  Use the equipment and accessories 

etc. in accordance with these 
instructions, considering working 
conditions and the work to be 
performed. Using the equipment for 
operations different from those 
intended could result in hazardous 
situations. 

  Always keep equipment components 

(engines, hoses, handles, controls, 
frames, housings, guards etc) and 
accessories (cutting tools, nozzles, bits 
etc) properly maintained. Keep the 
equipment clean and, where
