WARNING! Read and understand all instructions. Failure to follow the safety instructions may result in electric shock, fire, and/or serious injury.

1.1 Work Area Safety
1.2 Electrical Safety

2. Power Tool Use and Care

3. Personal Safety

Causes and Operator Prevention of Kick-back

Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively upon the safety devices built into your saw. As a pruning saw user, you should take several steps to keep your cutting jobs free from accident or injury.

Residual Risks

Even with the intended use of the appliance there is always a residual risk, which can not prevent. According to the type and construction of the appliance the following potential hazards might apply:

5.2.2 Lubrication

NOTE: Chain life and cutting capacity depend on optimum lubrication. Therefore, the chain should be oiled before operation.

IMPORTANT: It is important to use bar and chain lubricant that is formulated to perform over a wide temperature range with no dilution required. Lubricant bottle and oil are not provided. These can be found at your local hardware store. Do not use dirty, used or otherwise contaminated oil. Damage may occur to the bar or chain. Use of non-approved oil will void the warranty.

Do not swallow. If swallowed, call a physician immediately. Keep out of reach of children. Store away from heat or open flame.

  1. Switch off the pruning saw and remove the battery.
  2. Place the pruning saw on a level surface with the Housing-Cover facing up.
  3. Clean the Guide Bar and Chain with a soft brush or solvent.
