OTHER MAINTENANCE
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.

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.
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.
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.
