CALIFORNIA Proposition 65 Warning: Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the State of California to cause cancer and birth defects or other reproductive WARNING harm. Foreword This manual provides information and procedures to safely operate and maintain this Wacker model.
Safety Information Safety Information This manual contains DANGER, WARNING, CAUTION, NOTICE and NOTE callouts which must be followed to reduce the possibility of personal injury, damage to the equipment, or improper service. This is the safety alert symbol. It is used to alert you to potential personal injury hazards.
Safety Information Operating Safety Familiarity and proper training are required for the safe operation of equipment! Equipment operated improperly or by untrained personnel can be dangerous! Read the operating instructions contained in both this manual and the engine manual and familiarize yourself with the WARNING location and proper use of all controls.
Safety Information 2.1.18 ALWAYS guide the saw in such a way that the operator is not squeezed between the saw and solid objects. Special care is required when working on uneven ground or when compacting coarse material. Make sure to stand firmly when operating the machine under such conditions.
Safety Information Service Safety Poorly maintained equipment can become a safety hazard! In order for the equipment to operate safely and properly over a long period of time, periodic maintenance and occasional repairs are necessary. WARNING 2.3.1 DO NOT attempt to clean or service machine while it is running. Rotating parts can cause severe injury.
Safety Information Hazard Symbols Symbol Meaning EXPLOSIVE FUEL Gasoline is extremely flammable and its vapors can explode if ignited. Store gasoline only in approved containers, in well-ventilated, unoccupied buildings, away from sparks or flames. Do not fill the fuel tank while the engine is hot or running, since spilled fuel could ignite if it comes in contact with hot parts or sparks from ignition.
Safety Information Damage Prevention Messages Other important messages that are designed to help prevent damage to your Wacker BFS Series Concrete Saw, other property, or the environment are preceded by the word NOTICE. NOTICE: Your Wacker BFS Series Concrete Saw or other property could be damaged if you don’t follow instructions.
Technical Data Saw Features The Wacker BFS Series Concrete Saw is designed for wet or dry, general application sawing. The heavy duty steel, one piece box frame is precision jig welded and reinforced. This precisely reinforced steel construction with balanced weight distribution and ergonomic handlebars assures straight and accurate cutting as well as ease of operations preventing fatigue.
Technical Data Tach / Hourmeter A digital readout tach/hourmeter is factory installed on the BFS Series models . When the engine is running, the display will indicate the engine’s RPM. When the engine is shut off, the display will switch to run time, initially in minutes, and then switching to hours after the first hour of operation.
Preparation Unpacking, Assembly and Preparation Your Wacker BFS-Series has been shipped from the factory fully assembled and requires only minimal service to insure proper machine preparation prior to use. The following instructions should be followed closely. Carefully remove carton, packing materials and the Wacker BFS-Series saw from the pallet.
Preparation Add Oil To fill the crankcase with oil, place the engine level. In order for this to be accomplished the blade must not be installed, and the depth adjustment must be down (until the engine is level). Refer to the manufacturer’s instructions for details on the type and amount of oil required.
Preparation Mounting the Blade When mounting the blade, locate the direction arrow on the blade and install the blade in the proper orientation. The blade rotates clockwise when viewed from the right side of the saw. The blade must be properly fitted over the blade shaft and drive pin. The drive pin must project through the hole in the blade and into the flange for proper performance.
Operation Saw Operations This section of the manual describes the operating procedures, and safety precautions for proper use of this concrete saw. This saw is intended for industrial applications by experienced operators. It is to be operated in conformance with applicable federal, state and local codes or regulations pertaining to safety, air pollution, noise, etc.
Operation Buried or Concealed Hazards Prior to operation of this machine the operator must determine the existence and location of any subsurface features which may be hazardous or could damage the equipment (i.e. electric cable, natural WARNING gas line, etc.). Operation in Enclosed Areas The operator is cautioned not to use this equipment within enclosed spaces.
Operation Maneuvering the Saw NOTICE: Raise the blade as high as possible when maneuvering so that the blade will not strike the pavement. The blade is spinning whenever the saw is running. WARNING The speed control lever for the hydrostatic transmission is adjusted at the factory to provide approximately 40 ft/min maximum in forward and 20 ft/min maximum in reverse with the engine running at full throttle.
Operation Saw only as deep as the specifications and job conditions require. Remember, airflow helps to cool the blade during dry cutting. Cutting too deep with one pass, or exerting excessive forward or side pressure can be dangerous. Step cut in increments of 2 inches (50 mm) or less, for the best results.
Operation If the saw should stall for any reason, raise the blade out of the cut before restarting the engine! When lowering the blade into a partially made cut, the blade must be perfectly aligned within the cut before starting to saw again. DO NOT force the blade into the material by lowering the blade too fast.
Operation 5.1 Cutting with the Blade on the Left Side Left side cutting can be easily accomplished by moving the blade guard to the left hand side of the saw belt guard using the following steps: 5.12.1 Turn kill switch to off position. 5.12.2 Disconnect water hose from blade guard.
Maintenance Maintenance Periodic maintenance including cleaning, lubrication, tensioning of drive belts, and inspection for wear and damage are routine servicing procedures. Following the procedures as outlined in the following table can prevent serious damage or malfunctioning of the machine and aid in preserving the useful life of saw blades. Before servicing the saw or engine, always turn the kill switch to the off position.
Maintenance Shut off the engine before performing any maintenance. If the engine must be run after a maintenance operation make sure the area is WARNING well ventilated. The exhaust contains poisonous carbon monoxide gas! Exposure can cause loss of consciousness and may result in death.
Maintenance Controls Stiff or sluggish response of controls must be corrected immediately. Periodically clean and lubricate the throttle cable, the throttle and choke controls. The frequency of this maintenance will depend on the utilization rate and the amount of dust. After performing any maintenance on controls, saw responsiveness must be checked before the initiation of sawing operations.
Maintenance 6.8.5 Place the transmission in neutral by moving the transmission control arm back and forth while manually rotating the transmission pulley. When the pulley spins freely and no movement of the drive chain is observed, the neutral position has been obtained. 6.8.6 Tighten the cable clamp.
Maintenance 6.10 Electrical System A fuse protects the battery charging circuit. The fuse and the battery are the only user serviceable parts of the electrical system. A short circuit or a battery connected in reverse polarity will blow the fuse. Refer to the Honda engine manual for the location and type of fuse.
Troubleshooting Saw Features When trouble occurs, Be sure to check the simple causes which, at first, may seem too obvious to be considered. Refer to the table below for problems and their possible causes. Cause Loose Oil Level Cooling Water in Dirty Loose Transmission...
