Fieldmann FZP 2001-E: 7. CHAIN BRAKE WITH PROTECTION AGAINST RECOIL

control, the recoil dangerous zone can get closer to the notch and thus cause recoil. Cutting

by means of the chain bottom part (at the log upper side) pushes the saw forward. This

pushes the power against the tree and provides constant support as well as gives more

control over the saw to the operator and subsequently the control of recoil dangerous zone.

Observe the instructions for maintenance and sharpening of chain and guide. When

replacing chains and guides use only the options recommended by the manufacturer. See

„Technical Data“.

The smaller the radius at cutting with the guide end, the smaller the risk of recoil occurrence.

Using the cutting device and maintaining sharp chain significantly reduces the risk of recoil

power.

7. CHAIN BRAKE WITH PROTECTION

AGAINST RECOIL

Saw is equipped with an automatic brake that stops chain movement if there is recoil at

cutting. The chain brake reduces the risk of accident but only the operator can prevent accident

occurrence.

ATTENTION! Pay high attention when operating chain saw and do not allow any contact

with a foreign object in the recoil dangerous zone.

Brake (Fig. 8, A) turns on either manually (using left hand) or automatically by means of

inertia force at the weight located under the front cover. Nevertheless once it is activated, the

protection mechanism against recoil works in the opposite direction against recoil power.

Saw features a sliding connector that protects saw against overload. If chain stops although

motor is on, saw was overloaded. Reduce the push on saw to such extent till the chain turns

on again. In case the saw is stuck inside tree, stop the saw immediately and release it.

Brake can also be activated manually by lowering front protective cover (Fig. 8, B)

downwards to the guide.

The purpose of protective guard against recoil is not only the activation of chain brake. Its

another important function is to reduce the risk of contact with saw chain in case an operator

loses control over the the grip of front handle.

Use chain brake as a „parking brake“ when you move the saw or put it on ground. Besides

automatic turning on in case of recoil the brake can also be activated manually and must be

activated in case of unintentional contact with rotating chain.

You can release brake by pulling protective guard in the backward direction to front handle.

As it has been stated, recoil is quite dangerous and occurs very quickly. Most of recoils

is weak and when they occur, chain brake does not turn on. When such a situation happens,

it is key for you to maintain firm saw grip and not to let it fall.

OPERATING INSTRUCTIONSELECTRICAL CHAIN SAW

Chain brake with protection against recoil

Chain brake can be activated manually or by means of inertia force depending on recoil

power and on saw direction in relation to the object which got in touch with recoil dangerous

zone.

- When recoil is too strong and your left hand is too far from protective guard, chain brake gets

activated through the inertia force of the chain brake against recoil power.

- When recoil is weak or your left hand is close to protective guard, chain brake is activated

manually by means of your left hand.

If chain saw is turned to a side and the operator holds the side of front handle, in case of

recoil the protective guard does not hit your left hand and thus chain brake does not get

activated. In such a situation inertia is the only way how to activate chain brake but similarly

as in case of manual activation this procedure need not work in every situation.

Control of brake belts

ATTENTION! Before cleaning or maintenance works always pull the plug out of mains

socket.

ATTENTION! Clean saw regularly.

Remove sawdust, resin and other dirt from chain brake and connector drum. Wear and dirt

have an impact on chain brake functionality.

Check regularly brake belts and make sure their thickness is no less than 0.6 mm.

Control of protective guard against recoil

ATTENTION! Before cleaning or maintenance works always pull the plug out of mains

socket.

ATTENTION! Examine machine properly.

Check any visible protective guard defects such as cracks.

Move protective guard forward and backward. Make sure that it moves freely and nothing

prevents its movement.

Control of manual function of chain brake turning on

ATTENTION! Before repair or maintenance works always pull the plug out of mains socket.

Check chain brake daily or at each use. During operation hold saw firmly with your left hand

at front handle and with your right hand at rear handle. Turn your left wrist and touch

protective guard which activates chain brake without having to release the front handle. The

chain should stop immediately.

If chain brake does not work properly, have it repaired in an authorized service facility.
