Adjusting The Chain Tension; Chain Lubricant - SNOWJOE SUN JOE 24V-HCS-CT Manual Del Operador

• Check that the chain is tensioned correctly, sharp and
there are no signs of any damage;
• Check that hand grip and protection devices are clean
and dry, correctly mounted and securely fastened to the
machine;
• Check that the On/Off switch and the safety lock button
move freely without forcing and return automatically and
rapidly back to their neutral positions;
• Check that the On/Off switch remains locked until the
safety lock button is pressed;
• Make sure the ventilation slots are not clogged with
sawdust or debris;
Break-in Time for New Chains
For safety operation, it's recommended to run through the
below break-in tips every time a new chain is installed.
1. Remove the battery and adjust the chain tension.
2. Insert the battery and switch on the pruning saw and
leave the motor running idle for approx. 5 minutes.
3. Remove the battery and check the chain tension again. If
necessary, re-tighten the chain.
4. Afterwards make only easy cuts for approx. 30 minutes.
Always ensure sufficient lubrication of the saw chain! Only
use the pruning saw for heavier cuts and greater cutting
depths after the break-in period.

Adjusting the Chain Tension

WARNING!
Use protective gloves when handling the
bar and chain.
1. Make sure the pruning saw is shut off and the battery is
removed. Loosen the sprocket/chain end cover a little by
turning the end cover knob counterclockwise (Fig. 4).

2. Use the equipped hex key wrench to turn the
chain adjusting screw clockwise to tighten, turn it
counterclockwise to loosen. A cold chain will be correctly
tensioned when there is no slack on the underside of the
guide bar; the chain is snug, but it can be turned by hand
without binding (Fig. 5).

3. Retighten the end cover knob. Using a screwdriver, run
the chain along the guide bar to check that it moves
smoothly.

Chain Lubricant

IMPORTANT! Only use a good quality bar and chain oil
designed specifically for use with chain saws to ensure optimal
lubrication of the cutting parts. Do not use oil containing
impurities.
IMPORTANT! The chain lubricating oil is bio-degradable. The
use of mineral oil or engine oil can have a serious impact on
the environment. It is essential that you use good quality oil to
lubricate the cutting parts effectively. Used or poor quality oil
does not guarantee good lubrication and reduces the lifespan
of the chain and bar.
Before lubricate the pruning saw, clean the guide bar and saw
chain with a soft brush. Then drop the oil between the chain
and the bar. Insert the battery and switch on the pruning saw.
The oil will be evenly distributed over the chain. For optimal
cutting result, lubricate the saw every 30 minutes during
operation. When storing the unit for a long period of time (3
months or longer), be sure the chain is lightly lubricated; this
will prevent rust on the chain and bar sprocket (Fig. 7).
