General Safety Instructions for Power Tools

Warning! Read all safety directions and instructions.
Omissions in the compliance with safety directions and instructions can cause electric shock and fire and/or severe injuries.

Retain all safety directions and instructions for future use.
The term “Power Tools” used in the safety instructions refers to mains- operated power tools (with power cord) and battery-operated power tools (without power cord).

Work area safety

• Keep work area clean and light. Cluttered or dark areas will cause accidents.
• Do not operate power tools in explosive and flammable atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks, which may ignite the dust or fumes.
• Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control of power tool.

Electrical safety for battery charger

• Power tool plug must match the outlet. Never modify the plug in anyway. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electrical shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool out-doors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

Cutting control mode
The PV400 electric pruning shears has two cutting control modes:

• Non-progressive cutting control
• Progressive cutting control

NON-PROGRESSIVE CUTTING CONTROL
When the pruning shear is turned on, the non-progressive cutting control is predetermined, that is, when the trigger is actuated the blade performs the cutting action, and when the trigger is released the blade opens.

PROGRESSIVE CUTTING CONTROL
To change the control mode, you must hold the trigger for 2 seconds until you hear an audible warning (a beep), which indicates that you have changed from normal cut control mode to progressive cut control mode.
In the progressive cutting control the blade moves according to the depth of the trigger drive, that is, if the trigger is activated halfway, the blade moves progressively halfway through its opening.

Opening change (only in progressive mode)
The PV400 shears incorporates a system of change of opening with memory. It means that we can adjust the opening of the head in function of the diameter of cut wished.
In the progressive cutting control mode, the cutting diameter can be adjusted and a smaller cutting diameter can be set, for which the position of the blade at the desired cutting diameter must be maintained for 1 second and an audible warning will sound (a beep) indicating that the selected cut-off opening diameter has been memorized.
To return to maximum opening, we keep the trigger pressed until two audible beeps are heard (two beeps), which indicates that the opening memory has been removed.

Maintenance & Cleaning

Tools to be repaired must be sent to Customer Assistance Service. Use original part keeps the tool good condition and safe.
Switch off the battery power and disconnect the toolbefore to check, maintain and repair the pruning shear, to avoid risk of unexpected actuating of the tool.
Warning!
In particular situations of very hard use, the blade and the handle could reach high temperatures. It is recommended to handle the pruner with care, using protective gloves.

Please wear glove before you check the blade sharp or not, that’s avoid blade hurt you. Check the pruning shear frequently, this will keep tool safe and reliable.

• Check the pruning shear frequently, this will keep tool safe and reliable.
• Don’t flush the tools or put it in water, it will cause short circuit or damagethe device.
• Keep ventilation, motor and handle cleaning, always use feather clean the device. Don’t use cleanser flush device, it will rust parts.
• Clean the blade after every use, protect by oil or spray protection.
• After continuous work for 8 hours, please open the trigger cover protection of the equipment and clean up wood chips and other impurities

Sharpening

• Sharpening is very important to keep blade in good condition and ensure long life.
• The tool have attached accessory to sharp blade, always check blade is in good condition before to start work. Of course, the frequency of sharpening depends on the nature of the sheared wood (hardness and diameter), pruning rate and sharpening tools (special abrasive tools are provided).
  As a result, the blade must be checked frequently during the initial period of use to determine the appropriate grinding time (check every 15 minutes and you will quickly calculate)

Greasing of the blades
The greasing of the blades has sto be repeated each 2-3 working days to guarantee the correct performance of the tool and to avoid the seize of the blades.

• Open the blades of the pruner.
• Turn off the tool and remove the battery.
• Apply the grease between the moving blade and the fix blade (see the picture below).
• Put together the battery and the tool.
• Turn on the pruner and pull the trigger some times to get the grease through the blades.
• Clean the blades from the grease leftover.

Greasing and blade replacement
General maintenance, cleaning, lubrication and blade replacement requires some disassembly and assembly of your pruner.
The cover is fastened to the pruner by 2 screws. The center bolt is secured with an adjustable gear nut which is locked into place by a gear nut clip. The gear nut clip is secured by a single bolt.
With the removal of the of the cover, adjustment clip, gear nut, and center bolt you can access, maintain, clean, lubricate and replacement of blades when necessary.
