Maintenance, Blade Shaft V-Belt Tension

10 Maintenance

(See Figures 1-6)

Before performing any maintenance, ALWAYS park the machine on a level surface with the Engine OFF and the Engine Start Switch (1H) in the “0” (OFF) position.

After each use CLEAN the machine.

LUBRICATION:

ENGINE OIL: Check daily (6B). Change Engine Oil and Oil Filter (6H) after every 100 HOURS of operation. See engine manual for oil type to use. 15W40 CD, CE is generally recommended. (6B) Capacity is 8.5 quarts (8.0 liters) with filter (6H). Align oil level with upper mark on dipstick (6B).

Lubricate every 100 hours:

•Front Axle Pivot Bearings (4C)

Lubricate every 250 hours:

•Bladeshaft Seals and Bearings (4A) 2 Pumps only

HYDRAULIC SYSTEM:

Refer to Section 12 - “Hydraulic System”

ENGINE GEARBOX (3A):

•Change oil after every 500 hours of operation. Use SAE 75W90 synthetic gear lubricant. Capacity is

32 oz.

•Drain cooling water from Water Drain Valve (3C) to prevent rust and freeze damage.

COOLING SYSTEM:

The engine cooling fluid is 50/50 anti freeze /water mixture.

•Clean the Radiator Air Filter Element (1DD) every 50 hours or when required, replace if damaged. Always keep Radiator Air Filter Element (1DD) in place.

•Check hoses and hose clamps for damage and looseness. Tighten or replace as required.

•Check Coolant Freeze Protection yearly.

•Flush and Clean radiator and cooling system every 500 hours.

•Maintain at least 1/4 full coolant level in Radiator Coolant Recovery bottle (1Y) when engine is cool.

AIR FILTER :

•Clean the Air Filter Outer Element (5A) when the Restriction Indicator (1N) Red Signal appears. DO NOT clean the Inner Safety Element (5A)!

To change or clean the air filter element:

•Remove the Air Filter Housing (5A) by opening the three (3) Air Filter Housing Clamps, and pulling the housing off.

•Pull the Air Filter Outer Element out of the filter housing and replace, or clean by using low pressure compressed air [2.75 bars (40 psi - MAX)] from the inside out. DO NOT clean the filter element by tapping it on the ground or other objects, this will damage the filter element!

•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 :

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.

To Tension V-Belts:

•Turn Engine Start Switch (1H) to the “0” (OFF) position.

•Using the Blade Shaft Wrench, loosen the horizontal clamping bolts (3K) at the front of the machine.

•Turn each of the two (2) vertical Tensioning Bolts (3J) [at the front of machine, below the Gear Box (3A)] CLOCKWISE until the V-Belts (3M) are tight.

•Replace V-Belts(3M) in complete sets only.

•For optimum V-Belt tension use GoodyearTensionRite™ Strips, P/N 191368. TensionRite™ strips are supplied with belts purchased from Husqvarna.

Never tension V-Belts (3M) beyond the original factory tension. Loose V-Belts result in poor saw performance and short belt life.
