Intended Use

Mains-powered chainsaw for medium-duty domestic gardening tasks, such as felling small
trees, cutting logs and firewood.
WARNING: This chainsaw is designed for cutting wood ONLY, and must not be used with
other materials.

Unpacking Your Tool

• Carefully unpack and inspect your new tool. Familiarise yourself with all its features and

functions

• Ensure that all parts of the tool are present and in good condition. If any parts are missing

or damaged, have such parts replaced before attempting to use this tool

Before Use

WARNING: Ensure the tool is disconnected from the power supply before attaching or
changing any accessories, or making any adjustments.

INSTALLING THE CHAIN GUIDE BAR

Note: Do not touch the chain without wearing safety gloves.
1.   Place the Main Body (16), Guide Bar (4) and Saw Chain (3) on a secure flat surface
2.   Loosen the Sprocket Locking Knob (1) and remove the Sprocket Cover (2) (see image 1)
3.   Position the Saw Chain around the Guide Bar, and Drive Sprocket (13). Adjust the

Tension Wheel (17) by turning it anticlockwise to its least tight position, to fit the chain
over the Guide Bar and Drive Sprocket assembly

Note: Ensure that the chain is fitted the correct way round; the teeth on the top of the blade
should face forward, matching the symbol on the side of the Guide Bar (see image 2).
4. Hold the Guide Bar so that the Saw Chain is fully extended around the Drive Sprocket.

Ensure the Tension Wheel is positioned so that its locating lugs fit into the slotted hole of
the Guide Bar (see image 3)

5. Refit the Sprocket Cover and tighten the Tension Dial (11) to remove excessive slack from

the Saw Chain

Note: The Saw Chain should remain in the Guide Bar guide and should be properly seated
around the Drive Sprocket.
6. Tighten the Sprocket Locking Knob (1), ensuring blade and Saw Chain remain correctly

seated (see image 7)

Tensioning the chain

1. To tension the chain, loosen the Sprocket Locking Knob (1) (see image 7) until the

Tension Dial (11) is free to turn

Note: The Tension Dial only needs to be adjusted in small increments to give different
variations of chain tension. DO NOT over/under tighten.
2. Turn the Tension Dial (see image 8) in a clockwise direction until the chain is so tensioned

that you can raise the chain in the middle of the Guide Bar by approx. 3-4mm only (see
image 9)

3. Retighten the Sprocket Locking Knob (1) by turning it clockwise.
• If the Saw Chain (3) sags, or if drive links can be pulled out of the Guide Bar, adjust the

chain tension as outlined in ‘Adjusting chain tension’ in the ‘Maintenance’ section of this
manual

WARNING: Saw Chains can also be overtightened. Tightening the Saw Chain too tightly risks
rupture during operation. There should be some play in the Saw Chain, but not enough for the
drive links to leave the Guide Bar. The chain must ALWAYS be able to move freely and easily
on the Guide Bar.

Testing the Chain Brake

WARNING: ALWAYS wear cut-proof gloves when touching the Saw Chain (3) to avoid injury.
WARNING: The Chain Brake (6) is an important safety device of this chainsaw, protecting the
user in the event of kickback by stopping the Saw Chain rotation. The operator MUST ensure
its correct operation before EVERY use.
• Ensure the chainsaw is NOT running whilst performing the following checks:
1. Check manual Chain Brake operation by pushing the Chain Brake forward, in the

direction of the Guide Bar (4). The Saw Chain must not turn

2. Release the Chain Brake by pulling the Chain Brake towards the Front Handle (7), until it

reaches the end of its travel. The Saw Chain can be moved freely again

3. Hold the chainsaw horizontally, release your hand from the Front Handle and let the tip of

the Guide Bar hit a tree stump or other piece of wood on the floor (see fig. X). The Chain
Brake must engage, and the Saw Chain must not move

Filling with chain oil

WARNING: Be careful not to spill any oil. Thoroughly clean away any spilled chain oil, even if
bio-degradable chain oil is used. Be aware of slipping hazards!
1. Clean the chain oil reservoir area, including the Chain Oil Reservoir Window (9), and

remove all wood dust and dirt

2.    Open the Chain Oil Reservoir Cap (10) by turning it anticlockwise
3.    Fill with specialised saw chain oil. DO NOT overfill
4.    Immediately refit the Chain Oil Reservoir Cap, and close by turning it clockwise until

hand-tight and sealed

Operation

WARNING: Chainsaws are potentially dangerous high-speed wood-cutting tools. Special
safety precautions must be applied, to reduce the risk of personal injury. Careless or improper
use may cause serious or even fatal injuries. ALWAYS operate chainsaws with both hands.
Start and operate without assistance.
WARNING: ALWAYS wear the appropriate personal protective equipment when using this
chainsaw, including but not limited to safety glasses, hearing protection, forestry helmet with
impact-resistant face shield, gloves, cut-proof trousers and safety shoes.
WARNING: Immediately switch off the chainsaw in case of excessive motor noise or
vibration, development of smoke or smells, or if the chainsaw operates sluggishly or at
reduced performance.
Note: Before operating a chainsaw, inspect the work area for potential dangers, and consider
possible escape routes.

Switching on and off

WARNING:
1. Release the Chain Brake (6) by pulling the lever towards the Front Handle (7). Maintain a

firm grasp of the Front Handle

2. Press the Lock-Off Button (8) inwards to release the On/Off Trigger Switch (12). To switch

the chainsaw on, the Lock-Off Button and the On/Off Trigger Switch must be pressed
simultaneously

• To switch the chainsaw off, push the Chain Brake forwards and release the On/Off Trigger

Switch and the Lock-Off Button

Checking chain lubrication

• After starting the motor, the chainsaw operator needs to ensure that sufficient oil is

delivered to lubricate the chain, before starting work:

1. With the chainsaw on, disengage the Chain Brake (6) by pulling it back towards the Front

Handle (7)
