OPERATION
PREPRATION
Before each use, check the following items to ensure safe working conditions.
CHAINSAW: before beginning work, inspect the chainsaw for damage to the housing, the extension cable, the
saw chain and the guide bar. Never use an obviously damaged machine.
OIL TANK: check the fill level of the oil tank. Also check whether there is sufficient oil available while working.
Never operate the saw if there is no oil or the oil level has dropped below the minimum oil level mark in order
to prevent damage to the chainsaw. On average, an oil filling is sufficient for approximately 10 minutes of cutting
operation (depending the duration of pauses and the density of the workpiece).
SAW CHAIN: check the tension of the saw and the condition of the blades. The sharper the saw chain is, the
easier and more manageable operations will be. The same applies to chain tension. Check the tension every 10
minutes of operation to maximize safety. New saw chains in particular are subject to changes due to the heat cre-
ated by operation.
PROTECTIVE CLOTHING: make absolutely sure to wear the approrpiate close-fitting protective clothing such
as chainsaw-protective pants, gloves and safety shoes. Wear a safety helmet with integrated hearing protection and
a face guard to provide protection against falling and recoiling branches.
ADJUSTING THE TELESCOPING HANDLE
1. Unlock the telescope release lever so that the pole can freely extend outwards and inwards.
2. Extend it to the desired length and relock the telescope release lever to hold it in place.
ADJUSTING THE REAR HANDLE
The rear handle can be adjusted into three varying positions. Adjust it by pushing the handle rotation switch and
turning the handle to the desired position. The pole saw can only be used if the handle is in a fixed position.
CONNECTING TO THE MAIN SUPPLY
1. Connect the main cable to a suitable extension cord. Make sure the extension cord is designed to accommodate
the amperage (4.5A) of the pole saw.
2. Secure the extension cable against tractive forces and accidental unplugging by looping it through the cable
strain relief notch on the underside of the rear handle. Connect the extension cable to a nearby socket.
TURNING THE POLE SAW ON AND OFF
To turn ON, hold the pole saw firmly with both hands on each respective handle. Press and hold the safety switch
located on the lefthand side of the rear handle above the main power trigger. Press down the trigger to turn it ON.
The safety switch can now be released.
To turn OFF, release the ON/OFF trigger switch. Always unplug the pole saw from its power supply when fin-
ished.
