• Install Air Filter Outer Element by pushing it into the
housing.
• Install the Air Filter Housing (5A) and close the three
(3) Air Filter Housing Clamps (5A).
The three (3) Air Filter Housing Clamps (5A)
can NOT be closed unless the Air Filter Outer
Element is properly installed.
• Replace the Inner Safety Element once per year or if
it becomes damaged.
• Replace any damaged filters or gaskets.
• Check air hose and clamps for damage or looseness.
Tighten or replace as required.
Wheels and Hubs:
• Check for excess wear and looseness. Tighten or
replace as required.
FUEL FILTER :
• Replace Spin-On Fuel Filter (5F) every 500 hours.
11 Blade Shaft V-Belt Tension
(See Figures 1-3)
This saw is equipped with high tension banded V-belts.
The belts are properly tensioned at the factory but after
a few hours of operation they will stretch and become
loose. Re-tension belts as described below.
To Tension V-Belts:
• Turn ENGINE START SWITCH (1H) to the “0”
(OFF) position.
• Open ENGINE HOOD (6E): See Figure(s) 3-1/3-2,
Item 3-1D/3-2D for procedure.
• Using the BLADE SHAFT WRENCH (2J), loosen
the horizontal clamping bolts (3K) at the front of
the machine.
• Turn each of the two (2) vertical BELT TENSIONING
BOLTS (3-1J, 3-2J) [at the front of machine, below the
ENGINE GEARBOX (3-1A, 3-2A)] CLOCKWISE until
the V-BELTS (3-1M, 3-2M) are tight.
• Replace V-BELTS (3-1M, 3-2M) in complete sets only.
• For optimum V-Belt tension use Goodyear TensionRite™
Strips, P/N 542 19 13-68. TensionRite™ strips are sup-
plied with belts purchased from your dealer.
• Never tension V-BELTS (3-1M, 3-2M) beyond the
original factory tension. Loose V-Belts result in poor
saw performance and short belt life.
Replace all shields and guards. Never run Saw
with out all shields and guards in place.
12 Hydraulic System
(See Figures 1-6)
The hydraulic system on this saw is used to RAISE/
LOWER the Diamond Blade (2E), and to propel the
saw FORWARD and REVERSE. The hydraulic system
consists of a Hydrostatic Pump (5N), (2) Hydraulic Wheel
Motors (4F), Hydraulic Filter (5K), DC Lift Pump (5H),
Hydraulic Oil Reservoir (5J), Flow Control Valve (1U),
and Hydraulic Lift Cylinder (4G).
• Hydraulic Filter (5K) should be changed after the
first 50 hours of operation, then every 250 hours of
operation.
• Check Hydraulic Reservoir (5J) fluid level periodically.
Maintain oil level with SAE 15W40 API Class SE, CC,
CD motor oil. DO NOT OVERFILL, check oil level
when saw is level.
• Change hydraulic fluid every 500 hours of operation.
Fill Hydraulic Reservoir (5I,5J) with approximately 2.5
quarts of SAE 15W40 API Class SE, CC, CD motor
oil. DO NOT OVERFILL! Check oil level when saw
is level.
• The lowering rate of the saw can be adjusted using
the Flow Control Valve (1U) at the rear of the saw. If
the saw falls too quickly, turn the knob on the Flow
Control Valve (1U) CLOCKWISE until an adequate
lowering rate is set.
13 Important Advice
(See Figures 2-3)
• Tighten loose nuts and bolts regularly, particularly after
several hours of operation.
• Check V-Belt (3-1M, 3-2M) tension regularly.
Re-tighten V-Belts (3-1M, 3-2M) as necessary.
• Remove the Diamond Blade (2E) for storage. Store
it carefully.
• Check the water spray over the Diamond Blade (2E)
periodically.
• Tighten the Diamond Blade (2E) firmly on the Blade
Arbor (2C).
• Make sure the contact faces of Flanges (2B & 2F),
Diamond Blade (2E), and Blade Shaft (2I) are clean.
Store in a safe place out of reach of children.
Remove all adjustment tools and wrenches.
Store diamond tool in a safe place so it
cannot be damaged.
