Vibration and cold

It is believed that a condition called Raynaud's Phenome-

non which affects the fingers of certain individuals may be

brought about by exposure to vibration and cold. Expo-

sure to vibration and cold may cause tingling and burning,

followed by loss of colour and numbness in the fingers.

The following precautions are strongly recommended be-

cause the minimum exposure which might trigger the ail-

ment is unknown.

 Keep your body warm, especially the head and neck,

feet and ankles, and hands and wrists.

 Maintain good blood circulation by performing vigorous

arm exercises during frequent work breaks, and also by

not smoking.

 Limit the number of hours of operation.

Try to fill each day with jobs where operating the trim-

mer or other hand-held power equipment is not re-

quired.

 If you experience discomfort redness and swelling of

the fingers, followed by whitening and loss of feeling,

consult your physician before exposing yourself further

to cold and vibration.

 Failure to observe these instructions could result in damage

to your health.

Repetitive stress injuries

It is believed that over-using the muscles and tendons of

the fingers, hands, arms and shoulders may cause sore-

ness, swelling, numbness, weakness and extreme pain to

the areas just mentioned. Certain repetitive hand activities

may put you at a high risk for developing a repetitive

stress injury (RSI).

To reduce the risk of RSI, do the following:

 Avoid using your wrist in a bent, extended or twisted

position.

 Take periodic breaks to minimize repetition and rest

your hands. Reduce the speed and force in which you

do the repetitive movement.

 Do exercises to strengthen hand and arm muscles.

 See a doctor if you feel tingling, numbness or pain in

your fingers, hands, wrists or arms. The sooner RSI is

diagnosed, the more likely permanent nerve and muscle

damage can be prevented.

 Failure to observe these instructions could result in damage

to your health.

1. Chain tensioning screw

1. Oil filler cap

WARNING

 Never fill the oil reservoir or adjust the oiler with the en-

gine running.

NOTE

The oil reservoir has a capacity sufficient to provide about 40

minutes of cutting time (when set to deliver the minimum flow

rate, or about as long as you'll get from a tank of fuel).

1. Oil reservoir 2. Oil flow adjusting screw

CAUTION

 An increase in bar oil flow rate will speed oil consump-

tion, requiring more frequent checks on the oil reser-

voir. To ensure sufficient lubrication, It may be

necessary to check the oil level more frequently than at

fuel tank refills.

14

Before you start

The pump is set at the factory to deliver a minimum flow rate, but

it can be adjusted in the field. A temporary increase in oil flow is

often desirable when cutting things like hardwood or wood with a

lot of pitch.

Adjust the pump as follows:

1. Stop the engine and make sure the stop switch is in the OFF

position.

2. Place the product on its side with the oil reservoir up.

3. Using a screwdriver, turn the oil flow rate adjustment screw

in the desired direction:

 clockwise–decrease lubrication.

 anticlockwise–increase lubrication.

Operation

Preparations

 Check unit for loose/missing nuts, bolts and screws. Tight-

en and/or replace as needed.

 Choose the best work position for safety against the falling

object (Branch etc)

 Start the engine.

 Put on the strap.

Never stand underneath the branch you are cutting–be wary of

falling branches. Note that a branch may spring back at you after

it hits the ground.

Cutting Sequence

To allow branches a free fall always cut the lower branches first.

Prune heavy branches (large diameter) in several controllable

pieces.

Working Position

Hold the control handle with your right hand, and the shaft with

your left hand. Your left arm should be extended to the most com-

fortable position.

The shaft should always be held at an angle of 60° or less.

Typical applications

Standard cut(A):

The most convenient working position is a tool angel of 60°, but

any other angle may be used to suit the situation concerned.

Cutting above obstacles(B):

Thanks to the unit's long reach it is possible to prune branches

that are overhanging obstacles, such as rivers or lakes. The tool

angle in this case depends on the position of the branch.

Cutting on a work platform:

The unit's long reach enables cutting to be performed next to the

trunk without the risk of the work platform damaging other

branches. The tool angle in this case depends on the position of

the branch.

This product is designed especially for cutting branches. Never use this product for any other purposes. Never try to cut stones,

metals, plastics or any other hard objects.

Using for other purposes than cutting branches may damage the machine or cause serious injury.

WARNING

 Stop the product immediately if it suddenly begins to vibrate or shake. Inspect for broken, missing or improperly

installed parts or attachments.

 If a saw blade should bind fast in a cut, shut off the engine immediately. Push the branch or tree to ease the bind and

free the blade.

 Before starting the engine, make sure the saw chain is not contacting anything.

 Make sure the chain cover is in place when transporting and storing the pruner.

 When carrying the Multipurpose Engine with the pole pruner tool, the chain should be

pointing backward.

 Never transport the pruner or set it down with the engine running. An engine that's run-

ning could be accidently accelerated causing the chain to rotate.

16

Operation

Working techniques

Relieving cut:

To avoid tearing the bark, kickback or pinching the bar when

pruning thick branches, always start by performing a relieving cut

(1) on the underside of the branch.

To do this, apply the cutting attachment and pull it across the bot-

tom of the branch as far as the bar nose. Perform the cross-cut

(2).

Flush-cutting thick branches:

If branch diameter is more than 10cm, first perform undercut (3)

and cross-cut at a distance (A) of about 25cm from the final cut.

Then carry out the flush-cut (4), starting with a relieving cut and

finishing with a cross-cut.
