KNOW YOUR POLE SAW TOOL PURPOSE This pole saw is designed for limbing trees and cleaning up branches. Refer to the diagram below to become familiarized with the parts and controls of your 40V Max Lithium Ion Cordless Pole Saw. WARNING: When handling saw chains, always wear protective gloves.
ASSEMBLY AND ADJUSTMENTS WARNING: Do not plug in or turn on the tool until it is fully assembled according to the instructions. Failure to follow the safety instructions may result in serious personal injury. FILLING THE AUTO OIL SYSTEM This pole saw features an auto-oiling system to keep the chain and guide bar properly lubricated. The oil level indicator shows the remaining oil in the pole saw. If the oil level decreases to below one quarter capacity, refill it with the proper bar and chain oil.
ASSEMBLY AND ADJUSTMENTS ASSEMBLY OF GUIDE BAR AND SAW CHAIN 1. Place the saw body on a firm and level surface. 2. Rotate the cover release knob (Fig. 2 - 1) counterclockwise to remove the cover from the saw’s body. 3. While wearing protective gloves, wrap the saw chain around the guide bar, making sure that the teeth are aimed in the direction of rotation (Fig. 3). The chain should be properly set in the slot running along the entire outside edge of the guide bar. 4.

OPERATION PREPARATION Before each use, check the following items to ensure safe working conditions. POLE SAW: before beginning work, inspect the pole saw for damage to the housing, the saw chain and the guide bar. Never use an obviously damaged machine.
