ADDITIONAL ENGINE INFORMATION
Please see the Robin Operator’s Manual for additional information about servicing the engine.
The manual also has specific information about specifications,
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.
Belt
Inspect the blade drive 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 bearings 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 bar and controls clean and dry. Im- mediately clean any spilled fuel from the saw. Keep all open- ings and slot on the engine shrouding on the saw clean and open so air flows freely through the engine to insure proper cooling.
