OTHER MAINTENANCE

Guards

Check all guards for damage and proper function daily espe-

cially the blade block. Blade block and cover should be secure

to the saw and not damaged. Lexan side covers on the blade

block should move freely up and down.

Diamond blade

Inspect diamond blades daily for damage, cracks, secure fit

to the arbor, loss of segments, warping or overheating.

If any

blade shows any of these problems, discard the blade and

never use.

Saw controls

Inspect all controls for proper function daily.

Check all the in-

terlocks for operation especially the engine on/off switch

for proper operation.

Belts

Inspect the blade drive belt and transmission belt for cracks or

signs of wear. The belt tension is controlled by belt tensioner

and does not require adjustment. Inspect the belt tensioner for

free movement up and down. Insure the belt tensioner bear-

ings roll freely.

Blade shaft bearings

Lubricate the blade shaft bearings with 3 pumps of Lithium 12

based grease every 50 hours.

Cleaning

Clean the blade block of any excess concrete build up after

each use. Keep the handle bars and controls clean and dry.

Immediately clean any spilled fuel from the saw. Keep all

openings and slot on the engine shrouding on the saw clean

open so air flows freely through the engine to insure proper

cooling.

WARNING

Do not modify the saw! Use only Husqvarna Construc-

tion Products replacement parts. Use of unauthorized

parts may create a danger or damage the engine.

Skid plate

Inspect the skid plate daily for damage, excessive wear in the

blade slot, burrs on the concrete surface side, twisting and free

movement up and down when installed on the blade block.

Replace the skid plate with each new diamond blade. Never

reuse the skid plates or spalling and raveling may result.

Battery

The battery is maintenance free. If the battery ever requires

charging, use only a voltage regulated taper current charger

designed specifically for sealed lead acid gel cell batteries

rated at 2 amps or less (part # 505583501). A standard auto-

motive, or any other type, battery charger not designed specifi-

cally for sealed gel batteries will cause permanent damage to

the installed battery and void any warranty. Do not leave the

ignition key in the “ON” position as this will drain the battery.

WARNING

- Connecting and disconnecting a battery can cause

sparks and short circuits. Do not short battery ter-

minals by allowing a wrench or any other object to

contact both terminals at the same time.

- A spark or flame can cause a lead acid battery to

explode.

- Before connecting a battery, remove metal

bracelets, wristwatch bands, rings, etc. Use gloves

and protective glasses or face shield when working

with a battery.
