For wet use, fill in the water tank or connect the vacuum extractor and ensure that the vacuum hose is clear and it will follow the machine easily. Make sure the bonnet air filter on top of the engine is clean. It should be cleaned hourly. Check the engine oil level, screw the dipstick in to get reading. See to it the tank is fill up (see also “Storage Propane tanks). TANK and FUEL LINES ‐ The tanks has already been covered but do the fuel lines show any sign of wear and tear, such as cracks or any corrosion. Screw the brass fuel line fitting onto the tank service‐valve hand tight only. This connection MUST be secure because the service valve has a safety valve inside it, which will only open if the brass fuel‐line fitting is COMPLETELY seated into the service valve. WATER FLOW CONTROL UNIT The operator can choose the water sprayer in the front when the tap is in the horizontal position (Fig.4.1), the water will spray under the cover of the machine when the level is in the vertical position (Fig.4.2).The flow regulating valve located on the tank (Fig.4.2.1) is increasing or reducing the water flow to the working area – in front of the machine ...

Each additional weight weighs about 64 lbs or 29 kg. Each individual application, type and condition of surface, power capacity of the outlet, etc. will determine the number of weights you can use without tripping a breaker. The weight stacks on to three posts around the outer bowl (Fig.5.2). The additional weights depend on the tools; it is not always possible to add weights. Some tools work too aggressively and the machine can stop. The weight can be ordered with item number A 08.00.00.00. Figure 5.1 Figure 5.2 ...

Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 CHECK AND REPLACE EVERY 200 WORKING HOURS Every 200 working hours the operator should inspect all parts of the machine carefully. Most importantly, inspect and clean the tool plate connections, vacuum hoses and water tank. Also, check the water flow. Check the guard assembly. Make certain the wheels are clean and rotate properly. Inspect the control buttons. If there are defective control parts, they should be replaced immediately. Replace worn vacuum‐ and water hoses. Carefully inspect the seal rings and bearings of the grinding units, and replace any showing signs of excessive wear. For more information, refer to chapter troubleshooting below. Open the service cover on the motor base (Fig 7.2) (Fig 7.3) to check the chain with special lubricant for chains of the planetary chain. Lubricate and correct the sag if needed . For sagging correction (See TROUBLESHOOTING . Dismount the tool holders (See Troubleshooting) replace all parts (elastic element, buffers, sealers) with the slightest damage or consume. Return machine to authorized service center for overall checkup of the Engine. For Figure 7.2 Propane safety, have the machine serviced by a Certified Technician, including emission check. CHECK AND REPLACE EVERY 400 WORKING HOURS Besides the checks of 200 working hours, replace sealer and V‐rings like described in chapter “TROUBLESHOOTING REPLACING BELT AND PULLEY UNITS. Check if belts and bearings are in good condition, change if needed. ...

Superabrasive User Manual Original Language Lavina® 25G‐X 2/2015 8. TROUBLESHOOTING 8.1 ENGINE When troubles occur, be sure to check the simple causes which at first, may seem too obvious to be considered. For example, a starting problem could be caused by fuel starvation due to an empty propane cylinder or an unopened service valve. If you do not check for this, starter burnout could result. Some Troubles and solutions: Surging idle To smooth out the engines' idle characteristics, adjustment is provided by an idle screw on the lower left side of the carburetor as viewed from the operator's position. The screw is bright steel and 1/4" in diameter with a Phillips head on it. Rotating the screw clockwise will increase the idle speed and this should cure the "surging idle". If it does not, call our customer service. Engine starts and idles, but will quit as the throttle is advanced It is possible that the propane tank's service valve is faulty. To check for this, close the valve completely and then reopen very slowly while you listen for a "click" when the gas begins to travel through the valve. If you hear this very slight noise, the valve is only partially opening. This allows enough gas through to start and idle the engine, but not enough for full throttle operation. As the throttle is increased, allowing more air to enter the intake, the engine will quit from fuel starvation. Call your dealer or the factory for instructions on where to have the service valve replaced. Meanwhile, to get by, you can continue to open the service valve until you do not hear a “click" and then the engine will run normally. If it does not, call your customer service. Starter barely turns the engine over or the solenoid just clicks The battery is likely low in charge. This can be remedied by recharging the battery using a 12 Volt battery charger at 4.12 amperes. The battery is located on the left side of the propane tank holder under the battery cover. The positive post is the one with the RED cable attached to it. Follow the instructions that came with the battery charger. REMINDER: this will continue to ...
