aluminium.

3. Firmly tighten the clamping screw (E), however, be careful not to over-tighten as the screw is threading

into aluminium.

The collar features a spring loaded locking pin (F) and a

clamping screw (G). The system allows secure attachment of

poles without any tools required. Internally, the driven shafts

connect using a square drive coupling (H).

Extension poles and attachments that include a pole; for

example, chainsaw and hedge trimmer, are connected as

follows. Disconnection of parts is a reversal of the connection

procedure.

1. Position the collar (A) and pole (B) so the locking pin (F) and hole (I) are aligned.

2. Pull up and hold the locking pin, then insert the pole into the collar. It may be necessary to rotate the

pole so the internal square drive coupling engages. Push the pole fully into the collar, then release the

locking pin.

3. Rotate the pole until the locking pin "pops" into the hole, then firmly tighten (rotate right / clockwise) the

clamping screw (E) by hand.

Petrol Powered Pole Tools

When assembling extension

poles and attachments, do

NOT exceed 5 pole lengths from the engine

to the cutter. For example, no more than 3

extension poles between the drive shaft and

chainsaw attachment – see adjacent diagram

(extension poles are shown in yellow). Over

extending the tool may damage it and / or

render it a hazard and will void warranty. •

When the overall length of the tool exceeds

3m (10'), it may be necessary to have an

assistant help support the weight of the tool.

Cutting Guard Assembly

1. Bring the cutter guard (A) into position with the cutter drive shaft (B) as shown, and align the mounting

bracket (C) holes with the threaded inserts in the guard.

2. Secure the cutter guard to the bracket using 2 M5 cap screws (D).

3. Place the trimming blade (E) into position on the underside of the cutter guard and secure it using 2 self-

tapping screws (F). Be careful not to over-tighten the screws as they are screwing into plastic.

Concrete Vibrator Assembly

Do NOT use extension poles with the vibrator attachment.

The concrete vibrator attachment (where applicable) requires assembly.

This attachment uses a slightly different connection method to "standard"

attachment collar due to the additional vibrational stresses.

1. Slide the vibrator collar (A) over the end of the drive shaft (B), with the

locking screw (C) and hole (D) in the drive shaft aligned. It may be

necessary to rotate the pole so the internal square drive coupling

engages.

2. Firmly tighten the locking screw, however, be careful not to over-

tighten as the screw is threading into aluminium.

3. Firmly tighten the 2 clamping screws (E), however, be careful not to over-tighten as the screws are

threading into aluminium.

Chainsaw Attachment Assembly

Do NOT attach or detach cutting tools when the engine is running. • Wear suitable gloves

when handling cutting devices. • Always check that the blades or cutting accessories are

undamaged, safe to use and are properly and securely fastened to the machine. • Ensure that the saw chain

is installed so it rotates in the direction of the cutting edges. • Do NOT use cutting equipment that is cracked,

bent, chipped or damaged in any way. Replace damaged parts.

The chainsaw attachment (where applicable) requires assembly.

1. Remove the chain drive cover (A) nut (B), then remove the cover from the chainsaw attachment.

2. Place the saw chain (C) into position and engage it with the

drive sprocket (D). Ensure that the sharp edges of the saw

chain cutters (AA) are facing the correct direction.

3. Place the chain bar (E) into position so the drive chain

cover stud (F) protrudes through the slot in the chain bar,

and that the chain tension spigot (G) engages with its hole

in the chain bar (it may be necessary to adjust the position

of the chain tension spigot – see Adjusting Saw Chain

Tension).

4. Wrap the chain around the chain bar so it is sitting in the

chain bar groove.

5. Place the chain drive cover in position over the drive cover stud. Re-install the drive chain cover nut, and

tighten to "finger-tight" only at this stage. Ensure you thoroughly read Adjust Chain Tension before

proceeding.

Saw Chain Lubricant

The saw chain and drive system for the chainsaw accessory requires adequate lubricant of the correct type

to operate safely and efficiently. The machine is shipped without chain lubricant. Check the chain lubricant

level and ensure that it is at the recommended level. See Chain Lubricant.

Saw Chain Tension

Ensure that the saw chain is correctly tensioned and the chain drive cover nuts are properly

tightened before use and during cutting. • The saw chain will "stretch" with use, so it is

important to check chain tension before and during use • Wear suitable gloves when handling cutting

devices. • Do NOT check chain tension with the engine running. • Do NOT adjust chain tension with

the engine running.

Correct saw chain tension is extremely important in terms of both machine efficiency and operator safety.

Check chain tension before each use. Check chain tension frequently during use – whenever the machine is

put down (engine MUST be stopped first).

Checking Tension

Ensure engine is not running when adjusting chain tension.

•The saw chain should fit snugly into the groove in the chain bar and it must be possible to pull the chain

along the bar with a gloved hand. You should be able to lift the saw chain just out of the chain bar groove

without excessive effort.

•If the chain "sags" under the chain bar or can be lifted well out of the chain bar groove, it is too loose.

•If the chain is snug in the chain bar groove but cannot be lifted out slightly or be pulled around the bar by

hand, it is too tight.

Adjusting Tension

1. Clean the chain (if necessary), chain bar and tensioning mechanism.

2. Ensure the cover nut holding the chain drive on is only "finger-tight".

3. Lift and hold the end of the chain bar up, then using a suitable screwdriver, rotate the adjustment screw

(D) as required – rotate right (clockwise) to increase tension; rotate left (anti-clockwise) to reduce

tension.

4. While still holding the end of the chain bar up, securely tighten the cover nut with the tools provided.

5. Check chain tension and re-adjust, if necessary. Ensure the cover nut is loosened again to "finger tight"

before making tension adjustments. Once the tension is correct, ensure the cover nut is securely

tightened with the tools provided.

Attaching Cutting Tools

Do NOT attach or detach cutting tools when the engine is running. • Wear suitable gloves

when handling cutting devices. • Always check that the blades or cutting accessories are

undamaged, safe to use and are properly and securely fastened to the machine. • Ensure that brush cutter

and brush saw blades are installed so that they rotate in the direction of the cutting edges. • Do NOT use

cutting equipment that is cracked, bent, chipped or damaged in any way. Replace damaged parts. • The

toothed cutter and brush saw are not designed to be re-sharpened.

Cutting tools may include the following types. Use the cutter appropriate for the job, type of grass/brush etc:

Toothed Cutter

3-Blade Cutter

8-Tooth Cutter

Brush Saw

Lawn Edger

1. Place the drive washer (A) on to the drive shaft (B) protruding from the attachment head (C). Ensure that

the grooves in the washer align with the splines on the drive shaft.

2. Place the attachment on to the drive washer:

For the brush cutter and saw type attachments:

a. Place the cutter attachment (D) on to the

drive washer. Ensure that direction of the

cutting teeth or blades faces the direction

shown by the blue arrow. Ensure that the

hole in the centre of the attachment sits

squarely on the raised portion of the drive

washer.

b. Place the cup washer (E) over the drive

shaft, then secure the assembly with the

nut (F). The thread on the drive shaft is

"left-hand". This means that you must

rotate the nut to the left (anti-clockwise) to

screw it on as shown by the yellow arrow.

Firmly tighten the nut using the supplied spanner. To prevent the drive shaft from rotating as you

tighten the nut, insert a suitable object (G) (Allen key, screwdriver etc) through the hole in the

attachment head and into the hole in the drive washer when tightening – you may need to rotate

the drive washer until the holes are aligned. Remove the object when the nut is secured.

For grass cutting "bump" head:

a. Screw the grass cutting head (H) on to the drive

shaft. The thread on the drive shaft is "left-

hand". This means that you must rotate the

grass cutting head to the left (anti-clockwise) to

screw it on as shown by the yellow arrow.

Firmly tighten the grass cutting head by hand.

To prevent the drive shaft from rotating as you

tighten the grass cutting head, insert a suitable

object (G) (Allen key, screwdriver etc) through

the hole in the attachment head and into the

hole in the drive washer when tightening – you

may need to rotate the drive washer until the

holes are aligned. Remove the object when the

grass cutting head is secured.
