Ad usting Blade Clearance
Blade clea ance may be va ied but fo longe
blade life, a few thousandths clea ance should be
maintained. Blades should not be in actual con-
tact with each othe . Best esults may gene ally
be obtained with .002" clea ance on the ends
and .001" clea ance at the cente .
1. Move the handle down until am is at the
bottom of its st oke
2. Check clea ance between the blades, adjust to
obtain equal clea ance on both ends of am.
Opposing sc ews (P) on both ends of base cast-
ings will move bed in and out when bed clamp
bolts a e loose.
3. If clea ance of blade is othe than ecommended above, adjust nuts (Q) to obtain p ope
clea ance. This will align top blade with lowe blade. (Loosening inne nut and tightening
oute nut will pull blade and am fo wa d o dec ease blade clea ance.)
4. When final adjustment is complete, nuts should be locked against blade st aightene .
NOTE: Check clea ance while this is being done – 1/16 of a tu n can va y blade
st aightness app oximately .007".
Ad usting Clearance Of Ram Slides
Clea ance on am slides should be kept to a minimum but ca e should be exe cised to
p event binding. Adjust sc ews (R) evenly on both sides of am to obtain p ope clea ance.
