IMPORTANT SAFETY INSTRUCTIONS

WARNING: WHEN USING THIS TOOL, BASIC SAFETY PRECAUTIONS SHOULD ALWAYS BE FOLLOWED TO REDUCE THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL INJURY, INCLUDING THE FOLLOWING:

READ ALL INSTRUCTIONS.

Replacement Parts - When servicing use only identical replacement parts.

Polarized Plugs - To reduce the risk of electric shock, this appliance has a polarized plug (one blade is wider than the other) and will require the use of a polarized extension cord. The appliance plug will fit into a polarized extension cord only one way. If the plug does not fit fully into the extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A polarized extension cord will require the use of a polarized wall outlet. This plug will fit into the polarized wall outlet only one way. If the plug does not fit fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified electrician to install the proper wall outlet. Do not change the equipment plug, extension cord receptacle, or extension cord plug in any way.

Avoid Dangerous Environment - Don’t use hedge trimmers in damp or wet locations.

Don’t Use In Rain.

Keep Children Away - All visitors should be kept at a distance from work area.

Dress Properly - Do not wear loose clothing or jewellery. They can be caught in moving parts. Use of rubber gloves and substantial footwear is recommended when working outdoors. Wear protective hair covering to contain long hair.

Use Safety Glasses - Always use face or dust mask if operation is dusty.

Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the hedge trimmer. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.

Use Right Appliance - Do not use appliance for any job except that for which it is intended.

WARNING - To reduce the risk of electric shock, use only with an extension cord intended for outdoor use, such as SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJOW-A, SJTW-A or SJTOW-A.

Extension Cords - Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

Not Recommended

000173

To reduce the risk of disconnection of hedge trimmer cord from the extension cord during operating, use the hook complete described in this manual.:

Avoid Unintentional Starting - Don’t carry plugged-in hedge trimmer with finger on switch. Be sure switch is off when plugging in.

Don’t Abuse Cord - Never carry hedge trimmer by cord or yank it to disconnect from receptacle. Keep cord from heat, oil and sharp edges.

DANGER: RISK OF CUT!

KEEP HANDS AWAY FROM BLADES!

009414

Keep both hands on handles when power is on. Do not attempt to remove cut material nor hold material to be cut when blades are moving. Make sure trimmer is switched off and unplugged when clearing jammed material from blades. Do not grasp the exposed cutting blades or cutting edges when picking up or holding the hedge trimmer.

CAUTION: Blades coast after turn off.

Don’t Force Hedge Trimmer - It will do the job better and with less likelihood of a risk of injury at the rate for which it was designed.

Don’t Overreach - Keep proper footing and balance at all times.

Stay Alert - Watch what you are doing. Use common sense. Do not operate hedge trimmer when you are tired.

Disconnect Hedge Trimmer - Disconnect the hedge trimmer from the power supply when not in use, before servicing, when changing accessories

such as blades and the like.

Store Idle Hedge Trimmers Indoors - When not in use, hedge trimmer should be stored indoors in dry, and high or locked-up place - out of reach of children.

Maintain Hedge Trimmer With Care - Keep cutting edge sharp and clean for best performance and to reduce the risk of injury. Follow instructions for lubricating and changing accessories. Inspect hedge trimmer cord periodically, and if damaged, have it repaired by an authorized service facility.

If the power cord is damaged, disconnect the mains plug.

Inspect extension cords periodically and replace if damaged. Keep handles dry, clean and free from oil and grease.

Check Damaged Parts - Before further use of the hedge trimmer, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other condition that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service centre unless indicated elsewhere in this manual.

First Aid - For the event of a possible accident, please make sure that a first aid kit is always immediately available close by. Immediately replace any items used from the first aid box.

When engaging the extension cord, secure it to the tool's cord with the hook complete. Attach the hook about 100 - 200 mm from the extension cord connector. This will help prevent unintentional disconnection.

Waist cord hook

CAUTION:

Do not attach the holder of waist cord hook to other than the extension cord. Do not attach it in a position closer to the tool beyond the hook complete. Failure to do so may cause an accident or personal injury.

When using the waist cord hook, use the extension cord as a standard equipment. Using an extension cord available in the market may cause an accident or injury.

Attach firmly one hook of the hook complete to the tool's cord and the other hook of hook complete to the extension cord. Working with the tool with a sole hook only attached may cause an accident

and injury.

Using the waist cord hook helps to minimizing a risk of cutting off the extension cord unexpectedly caused by the loose extension cord.

Attach firmly the arm cord hook placing around your arm and pass the extension cord through the holder. The length of the arm cord hook band is adjustable.

NOTE:

Do not pass the extension cord through the band.

Do not force the opening of the holder. Failure to do so may cause deflection and damage to it.

Using the arm cord hook together with the waist cord hook is more helpful.

OPERATION

Refer to the Important Safety Instructions before operation.

CAUTION:

When operating the trimmer, keep extension cord behind trimmer. Never drape it over hedge being trimmed.

Be careful not to accidentally contact a metal fence or other hard objects while trimming. The blade will break and may cause serious injury.

Overreaching with a hedge trimmer, particularly from a ladder, is extremely dangerous. Do not work from anything wobbly or infirm.

5

Do not attempt to cut branches thicker than 10 mm diameter with this trimmer. These should first be cut with shears down to the hedge trimming level.

To cut a hedge top evenly, it helps to tie a string at the desired hedge height and to trim along it, using it as a reference line.

007559

CAUTION:

Do not cut off dead trees or similar hard objects. Failure to do so may damage the tool.

Hold the trimmer with both hands pull the switch trigger A or B and move it in front of your body.

009413

When operating the hedge trimmer, keep extension cord behind trimmer.

As a basic operation, tilt the blades towards the trimming direction and move it calmly and slowly at the speed rate of 3 - 4 seconds per meter.

Blade maintenance

Smear the blade before and once per hour during operation using machine oil or similars.

After operation, remove dust from both sides of the blade with wired brush, wipe off it with a rag and then apply enough low-viscosity oil, such as machine oil etc. and spray-type lubricating oil.

CAUTION:

Do not wash the blades in water. Failure to do so may cause rust or damage on the tool.
