material, adjust the blade pitch outward.
If the blade is cutting “out” at the bottom of the stock material, adjust
the blade pitch inward.
16.3 Re-tighten the blade guide mounting bolts. If all adjustments are
correct, the blades should lightly touch all BLADE GUIDE
BEARINGS (Items 20).
16.4 Check settings by making sample cuts in scrap stock before
doing production work.
Section 17: Adjusting the Clamp Vise
17.1 FOR ALL CUTS, — set the STATIONARY VISE JAW tern 50)
as close as possible to the right hand BLADE UIDE ASSEMBLY
(Item 18).
17.2 FOR SQUARE CUTS, — set the face of the STATIONARY
VISE JAW so that it is “square” with the saw blade, — to ensure
accurate “square” cuts horizontally across the stock material.
17.3 FOR ANGLED CUTS, —set the face of the STATIONARY
VISE JAW at the desired cut-angle with reference to the saw blade.
17.4 FOR PARALLEL STOCK, set the angle of the MOVEABLE
VISE JAW (Item 49) parallel to the STATIONARY VISE JAW.
17.5 FOR NONPARALLEL STOCK, — set the MOVEABLE VISE
JAW parallel to the stock mate rial, after it has been set in place on
the sawbed.
Section 18: Work Setup
18.1 Raise the saw head to its highest position.
18.2 Open the vise to accept the piece to be cut,
— by raising the CLAMP BAR (Item 47) on the MOVEABLE VISE
JAW (Item 49). Then slide it away from the STATIONARY VISE
JAW (Item 50).
18.3 Place the workpiece on the saw bed (Item
54). Long bar stock should be supported by a tripod type stand at the
same height as the saw bed.
18.4 Clamp the workpiece in the vise, by again raising the CLAMP
BAR and sliding it toward the workpiece until contact is made.
18.5 Drop the CLAMP BAR into a convenient slot in the clamp rack
(Item 46).
18.6 Tighten the vise by rotating the HANDWHEEL (Item 62)
clockwise until the workpiece is securely clamped in the vise.
Section 19: Positioning the Left Hand Blade Guide Assembly
Always position the left hand BLADE GUIDE assembly (Item 18) as
close to the MOVEABLE VISE (Item 49) as possible, as follows.
19.1 Loosen the BLADE GUIDE LOCK (Item 25) and slide the left
hand BLADE GUIDE CARRIAGE (Item 22) to the recommended
position.
19.2 Re-tighten the BLADE GUIDE LOCK before
cutting.
Section 20: Horizontal Operation
20.1 Raise the saw head so that the saw blade clears the stock
material.
20.2 Position the stock material in the vise and close the vise jaw tight
enough to hold the workpiece.
DO NOT REST THE BLADE ON THE WORKPIECEl
20.3 Re-check the position of the workpiece in the vise jaws.
20.4 When the position of the workpiece is cor rect, tighten the vise
firmly by hand, by turning the HANDWHEEL (Item 62)1
20.5 Position the left hand BLADE GUIDE
CARRIAGE and lock it in position by tightening the
BLADE GUIDE LOCK until it is moderately tight. DO
NOT OVERTIGHTEN!
20.6 Raise the saw head away from the work- piece as high as
possible.
20.7 Switch the saw “ON”.
20.8 Lower the sawhead by slowly turning the control knob on the
hydraulic DESCENT CYLINDER (Item 42) counterclockwise until
the saw head begins to descend allowing the saw blade to GENTLY
enter the material to be cut.
Lightly support the saw head by hand until a good introductory cut is
established.
After the blade has safely entered the material, it is no longer
necessary to support the frame by hand, since the natural feed of the
saw will complete the cut and the saw will switch “OFF”
automatically.
20.9 Repeat the foregoing opertions for each subsequent cut.
20.10 When through cutting remove the work- piece from the vise and
raise the saw head to its raised position.
It is best not to leave the saw head in the horizontal position, since in
this position the COUTERBAL ANCE SPRING (Item 56) is under
tension.
20.11 Clean saw and tidy up work area. See Sections 4 & 6.
Section 21: Re-adjusting the Counterbalance Spring
The COUNTERBALANCE SPRING (Item 56) assists the hydraulic
DESCENT CYLINDER in controlling the speed of the saw head
descent.
21 .1 To provide more counterbalance and a gentler rate of cutting as
well as longer blade life and smoother cuts, — TIGHTEN the
COUNTERBALANCE SPRING.
21.2 To provide less counterbalance and more vigorous rate of
cutting, — LOOSEN the COUNTER BALANCE SPRING.
