SAFETY INSTRUCTIONS FOR STRING TRIMMER

General string trimmer safety warnings:

Do not use the machine in bad weather conditions, especially when there is a risk of lightning. This decreases the risk of being struck by lightning.
Thoroughly inspect the area for wildlife where the machine is to be used. Wildlife may be injured by the machine during operation.

Thoroughly inspect the area where the machine is to be used and remove all stones, sticks, wires, bones, and other foreign objects. Thrown objects can cause personal injury.
Before using the machine, always visually inspect to see that the trimmer head (bump head) and cutting guard are not damaged and the trimmer head has trimmer line properly installed. Damaged parts increase the risk of injury.
Follow instructions for changing accessories. Improperly tightened trimmer head, cutting guard, or front handle securing nuts and bolts may either damage the string trimmer or result in it becoming detached.

Wear eye, ear, head, and hand protection. Adequate protective equipment will reduce personal injury by ﬂying debris or accidental contact with the cutting line or blade.
While operating the machine, always wear non-slip and protective footwear. Do not operate the machine when barefoot or wearing open sandals. This reduces the chance of injury to the feet from contact with the moving cutters or lines.
While operating the machine, always wear long trousers. Exposed skin increases the likelihood of injury from thrown objects.

Keep bystanders away while operating the machine. Thrown debris can result in serious personal injury.
Always use two hands when operating the machine. Holding the machine with both hands will avoid loss of control.
Hold the machine by the insulated gripping surfaces only because the trimming line may contact hidden wiring. Cutting line contacting a “live” wire may make exposed metal parts of the machine “live” and could give the operator an electric shock.

Always keep proper footing and operate the machine only when standing on the ground. Slippery or unstable surfaces may cause a loss of balance or control of the machine.
Do not operate the machine on excessively steep slopes. This reduces the risk of loss of control, slipping and falling which may result in personal injury.
When working on slopes, always be sure of your footing, always work across the face of slopes, never up or down and exercise extreme caution when changing direction. This reduces the risk of loss of control, slipping and falling which may result in personal injury.

Keep all parts of the body away from the trimmer head and trimmer line while the machine is operating. Before you start the machine, make sure the trimmer head and trimmer line are not contacting anything. A moment of inattention while operating the string trimmer may cause entanglement or personal injury from ﬂying debris.
Do not operate the machine above waist height. This helps prevent unintended trimmer head and trimmer line contact and enables better control of the machine in unexpected situations.
When cutting brush or saplings that are under tension, be alert for spring back. When the tension in the wood ﬁbers is released, the brush or sapling may strike the operator and/or throw the machine out of control.

Use extreme caution when cutting brush and saplings. The slender material may catch the trimmer head and trimmer line and be whipped toward you or pull you off balance.
Maintain control of the machine and do not touch trimmer head and trimmer line and other hazardous moving parts while they are still in motion. This reduces the risk of injury from moving parts.
When clearing jammed material or servicing the machine, make sure the switch is off and the battery pack is removed. Unexpected starting of the machine while clearing jammed material or servicing may result in serious personal injury.

Carry the machine with the machine switched off and away from your body. Proper handling of the machine will reduce the likelihood of accidental contact with a moving trimmer head and trimmer line.
Only use replacement cutters, lines, cutting heads and blades. Incorrect replacement parts may increase the risk of breakage and injury.
Inspect machine for damage upon striking a hard object or if there appears to be excessive vibration.

Keep hands away from any sharp device intended to limit the length of the ﬁlament line.

TRANSPORTING AND STORAGE

Unintentional starting may result in personal injury or property damage. Remove the battery before inspecting the string trimmer or carrying out any cleaning, maintenance, repair work, before storing, and any other time the string trimmer is not in use.

Grass trimming with a trimmer head Trimming

Hold the trimmer head just above the ground at an angle. It is the end of the cord that does the work. Let the cord work at its own pace. Never press the cord into the area to be cut.
The cord can easily remove grass and weeds up against walls, fences, trees and borders, however it can also damage sensitive bark on trees and bushes, and damage fence posts.
Reduce the risk of damaging plants by shortening the cord to 3.9 – 4.7in (10-12 cm) and reducing the motor speed.

Clearing

The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. CAUTION! This technique increases the wear on the cord.
The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc., than when coming into contact with trees and wooden fences.
When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head.

Cutting

The trimmer is ideal for cutting grass that is diﬃcult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.
Do not allow the trimmer head to constantly come into contact with the ground during normal cutting. Constant contact of this type can cause damage and wear to the trimmer head.

Sweeping

The fan effect of the rotating cord can be used for quick and easy clearing up. Hold the cord parallel to and above the area to be swept and move the tool to and fro.
When cutting and sweeping you should use full throttle to obtain the best results.

MAINTENANCE AND REPAIR

Correct maintenance is essential to maintain the original efficiency and safety of the machine over time.
Keep all nuts, bolts, and screws tight to be sure that the machine is in safe working condition.
Never use the machine with worn or damaged parts. Damaged parts must be replaced and never repaired.
Only use original spare parts. Parts that are not of the same quality can seriously damage the equipment and compromise safety.
If your machine has a malfunction, is damaged, or requires servicing: Contact dealer for Service.
