CAUTION
CAUTION: The blade depth is approximate and not exact. Many variables affect the exact blade depth such
as the exact diameter of a worn diamond blade. If an accurate depth must be cut, install the blade to be
used with the engine in the OFF position. Place the JS in a secure position that allows the blade to overhang
and be visibly measured at full blade depth. An example would be blocking the wheels with the engine in the
OFF position and lowering the JS blade along side a street curb. This will allow a measurement from the
bottom of the blade to the top of the curb.

adjustment
Figure 13 shows the JS in the maximum blade depth
cutting position with the top of the shaft collar
set at the lowest slot. To cut less than maximum
depths, loosen the socket head cap screws and
tap the collar with a hammer to loosen it. Then slide
the shaft collar up on the jack assembly lower
arm to the desired depth setting. The jack assembly upper arm will now stop on the shaft collar
controlling the blade depth. This shaft collar setting will also allow the JS to be quickly raised from
cutting position and then lowered back into cutting position at the same depth.
5.15 Hold the blade guard firmly and remove the bolt in the blade guard holding bracket. Lower the
blade guard down until the 2" caster wheel touches work surface. Reinsert bolt in the blade guard
holding bracket for future use.
5.16 Make sure the blade guard caster wheel and white dust brush at the blade guard base are firmly
touching the work surface. See section 8.2 for detailed instructions on adjusting the dust brush and
brush guard caster wheel.
