Choosing the Right Blade:
The rule of thumb for choosing a blade for a given application is that the harder and/or thinner the material the more teeth per inch is required. A list of TPI and mate- rials to be cut follows.
TPI | Material |
24 | Sheet Metal / Stainless |
14 | Metal / Wood w/ Nails |
10⁄14 | Soft Metals / Wood |
10 | Wood |
6 | Rough Cut Wood |
Stroke Length and Material Thickness:
The length of stroke for the G8599 Cordless Reciprocating Saw is 7⁄8". When material thickness exceeds 7⁄8" the blade is unable to evacuate the chips being pro- duced. Therefore, when cutting materials that are thicker than 7⁄8" it may be neces- sary to "clear the blade" occasionally. Simply let go of the trigger and allow the blade to come to a complete stop. Extract the blade from the cut and the chips should fall away. Insert the blade into the cut and continue cutting.
Choosing the Blade Speed:
Blade speed is controlled by the trigger. The more the trigger is depressed the faster the blade reciprocates. This allows speed control from
Using the right blade and blade speed will allow faster cutting operation, longer blade life and will prolong the life of the saw. The rule of thumb is the harder and/or thicker the material the slower the speed should be. This will require practice on the part of the operator. If blade seems to dull quickly replace and use slower blade speed. If cut- ting wood, most species allow faster speeds.
Never extract or insert the blade into workpiece with the blade in motion. Serious personal injury will occur.
