Figure 6. Types of Cuts (chain guard removed for

clarity)

1.Do not use a cutting force in excess of 45 lbs/20 kg. Excessive force causes the chain to slow down or stall and causes premature wear of the saw bar and chain.

2.Always maintain a high chain speed. High chain speeds produce the best results.

3.Always check that plenty of water is being expelled from the bar and chain. When the tool is running, water is directed to the interior of the bar and then out of several holes located along the top and bot- tom channels on the bar. If these holes become plugged, cutting debris will not be adequately washed away and will result in premature wear of the bar and chain.

4.Avoid aggressive/heavy plunge forces. Aggressive plunge force creates fragmenting of the concrete when the saw bar and chain exits and causes pre- mature bar and chain wear.

COLD WEATHER OPERATION

If the saw is to be used during cold weather, preheat the

hydraulic fluid at low power source speed. When using the normally recommended fluids, fluid should be at or above 50 °F/10 °C (400 ssu/82 centistokes) before use.

Damage to the hydraulic system or chain saw can result from use with fluid that is too viscous or thick.

USING THE WALL WALKER™

The Wall Walker™ lessens operator fatigue and effort during cutting by automatic insertion of the wedge into the cut, thus allowing the operator to apply leverage to the saw.

1.Position the Wall Walker™ in the "autofeed" position by pinning the lever arm at the lowest hole as shown in the illustration.

Start cutting with the DS06 until the cut is large enough to allow the tip of the wedge to insert into the cut. With the tip of the wedge in the cut, the opera- tor can easily apply leverage to the saw which will aid the cutting process and lessen operator fatigue and effort.

After the saw cuts approximately 1 to 2.5 in./25 to 65 mm, withdraw the saw only enough to allow the lever arm and wedge to reposition. After reposition- ing, continue cutting.

2.The Wall Walker™ can be positioned to the “parked” position by pinning the lever arm at the upper most hole. In this position, the Wall Walker™ is used as a bucking cleat.
