MQ PS4030 SAW — MAINTENANCE
Removal and Replacement
To ensure correct Blade Shaft/Wheel alignment this operation should be performed by and authorized Service Center.
Blade Alignment
Maintaining proper blade and drive system alignment will allow the saw to cut lines that are straight without much effort.Therefore the Blade Shaft Flanges MUST be equadistant to the sides of the saw,
The second requirement for the blade is that it MUST be square to horizontal (90o to flat surface). See Figure 52.
Drive System Alignment
In addition to Blade alignment, maintaining proper blade and drive system alignment will allow the saw to cut lines that are straight without much effort. Therefore the Front Wheels and Blade Shaft Axles MUST be at right angles to the frame edge.
In Figure 53 you see the distance "A" on the right side is shown as "A + .187"" which means that the distance between centers of the front and rear drive axles are 3/16" longer than on the opposite side. This will have the effect of causing the saw to "steer" slightly to the left. After becoming familar with the saws particular sawing characteristics, the operator may wish to have this alignment altered to fit his own preferences or to fit a particular application.

Drive System Alignment Adjustment
The drive wheels are aligned by adjusting the entire rear drive assembly.
1.Loosen the Wheel Mount Assembly Attachment Bolts just enough to move the Wheel Mount Assembly. Do not com- pletely loosen the Bolts.
2.Loosen and tighten the Alignment Jackscrew nuts to move the Wheel Mount Assembly, and thus the wheels, in the appropriate direction to achieve the desired alignment dis- tance. (See Fig. 53)
