Spare parts
The following parts of this product may be replaced by the consumer. Spare parts are available at an authorized dealer or through our customer service.
Spark plug: RCJ7Y/Champion, BM6A/Torch
Bar - chain type: 25cm - 3/8'', 1,3mm
Chain catcher
Replace a damaged or worn chain catcher with a new one of the same type.
1. Loosen the screw (Fig. 52, A) and remove it together with the chain catcher (13).
2. Fix a new chain catcher to the product.
Sprocket wheel
NOTE: It is not necessary to remove the saw chain (6) to lubricate the sprocket. Lubrication can be done on the job.
1. Clean the sprocket wheel (8).
2. Using a disposable lube gun, insert the needle nose into the lubrication hole (Fig. 53, A) and inject grease until it appears at the outside edge of the
sprocket (Fig. 53).
3. Make sure that the chain brake is disengaged.
Rotate the saw chain (6) by hand. Repeat the lubrication procedure until the entire sprocket has been greased.
Guide bar and saw chain maintenance
Most guide bar problems can be prevented merely by keeping the product well maintained. Incorrect filing and non-standard cutter and depth gauge settings
are the causes of most guide bar problems, primarily resulting in uneven bar wear. As the bar wears unevenly, the rails widen, which may cause the chain to
clatter and make it difficult to complete straight cuts.
If the guide bar is insufficiently lubricated and the product is operated with a saw chain which is too tight, this will contribute to rapid bar wear. To help mini-
mise bar wear, maintenance of the guide bar as well as the saw chain is recommended.
1. Disassemble the guide bar and saw chain in reversed order from assembly.
2. Check the oiling port (12) for clogging and clean if necessary to ensure proper lubrication of the guide bar and saw chain during operation. Use a soft wire
small enough to insert into the oil discharge hole (Fig. 54).
NOTE: The condition of the oil passages can be easily checked. If the passages are clear, the chain will automatically give off a spray of oil within seconds of
the product starting. Your product is equipped with an automatic oiling system.
3. Check the drive sprocket. If it is worn or damaged due to strain, have it replaced by an authorised service agent.
4. Clear residue from the rails on the guide bar (7) using a screwdriver, putty knife, wire brush or other similar tool. This will keep the oil passages open to
provide proper lubrication to the bar (7) and saw chain (6) (Fig. 55).
5. Check the guide bar 'rail' for wear: Hold a ruler (straight edge) against the side of the guide bar and 'cutter side plates'. If there is a gap between the
ruler and guide bar the guide bar 'rail' is normal. If there is no gap (ruler flush against the side of the guide bar) the guide bar 'rail' is worn and needs to be
replaced with a new one of the same type (Fig. 56).
6. Turn the guide bar 180° to allow even wear, thereby extending the life span of the guide bar (7).
7. Check the saw chain for possible wear and damages. Replace it with a new one if required. Experienced user can sharpen a dull saw chain (see section
"Saw chain sharpening" below).
8. Refit the saw chain (6) and the guide bar (7) as described under "Assembly".
