OPERATING INSTRUCTIONS

Experience is very important when running the 4200 saw. A skilled worker is highly recommended. Always do an inspection of the saw before starting the engine. Check the fuel (P) and oil level (Y) per the enclosed engine manual. SAE 10W/30 oil and unleaded gasoline with an 87 or higher octane should be used. The hydrostatic tansmission use Mobil DTE 26 hydraulic oil or equivalent (20W with viscosity of 68). Observe all safety regulations for the safe handling of fuel. Always check the engine oil with the saw turned off, completely lowered and the engine level! Check that all controls are in good work-ing order. Check for loose bolts or nuts. Check for fuel or oil leaks. Insure all guards are secure, undamaged and properly installed.

WARNING: Do not operate saw if there is a fuel leak!
WARNING: Do not operate the saw unless all guards, safety equipment and the engine kill switch are in place and operational! Check the air filter and clean or replace if necessary. Check for proper specification of blade and that the skid plate oper-ates properly. Check that the blade and skid plate are in good condition. Make sure the work site is clean, well lit and hazard free. To start the engine, turn the key switch (C) to the “ON” or “1” position to activate the rocker switches. Raise the saw by pushing the blade rocker switch (O) on the instrument panel to the full up position. Push the saw forward speed rocker switch (G) into neutral indicated by the red light (J) on the instrument panel. Make sure the red emergency stop button (D) is in the “up” position. The saw will not start unless the emergency stop is “up”. Close the engine choke (A) by pulling up on the knob. The closed choke position enriches the fuel mixture for starting a cold engine. The open choke position provides the correct fuel mixture for operation after the engine starts and for restarting a warm engine. Start the engine by turning the key switch (C) to “START” or “2” position and release once the engine starts. Slowly open the choke (A) by pushing down on the knob. Allow the engine to warm for a few minutes.

NOTE: The hour meter (F) runs when the key is “ON” even if the motor is not running.

WARNING: ASPHYXIATION HAZARD Running an engine in a confined or badly ventilated area can result in injury or death due to asphyxiation or carbon monoxide poisoning. Open the engine throttle lever to full open position for maxi-mum engine speed by pushing the engine speed rocker switch (I). Lower the front guide to the full down position by depress-ing the guide arm rocker switch (H).Line up the saw with the cut line using the front guide wheel, the rear guide (U), and the triangle pointer on the back of the blade block. Press the blade rocker switch (O) to lower the blade in the concrete slowly to the desired depth (S) shown on the back of of the blade block. Move the saw forward by tapping the forward speed rocker switch (G) until the desired cutting speed is reached. Keep the front guide wheel on the cut line to insure straight cuts. Make small adjustments by applying side pressure on the handle to keep the saw straight. Move the saw at about half speed for the first 200 feet to al-low the blade to develop good diamond exposure or open up and promote full blade life. Increase the forward speed of the saw until the blade and the engine are working at maximum efficiency. Increase the forward speed if the saw is pulling left. Decrease the forward speed if the saw is pulling right. Do not force the saw. When approaching a wall, raise the front guide and use the triangle guide at the back of the blade block to cut the last few feet. Do not hit the blade block assembly against any object. Damage may result. Slow the forward speed by pressing the forward speed rocker switch (G) until the saw stops. Press the blade rocker switch (O) to raise the saw out of the cut to full “UP” position. The self propel function of the saw will not operate with the unit in a raised position. Press the engine speed rocker switch (I) to lower the engine speed. Turn the engine kill switch to the
“OFF” or “0” position. Lower the saw to the down position.

WARNING: Do not leave the saw unattended while the engine is running! Always secure the saw from movement while unattended.

NOTE: Do not walk on the joints or transport equipment across the joints until the concrete fully hardens. Periodically, clean any excess concrete from inside the blade block, scrapers and blade block cover. Always clean the blade block assembly thoroughly before storing the saw.

WARNING: Before each use, carefully inspect the 4200 for any damage to any of its parts and components. Pay careful attention to any leakage of gasoline or oil. Under no circumstance should the 4200 or any of its attachments be operated if you find damage or are suspicious that something appears to be dam-aged.

WARNING: Do not modify the saw! Use only Husqvarna Construction Products replacement parts. Use of unauthorized parts may create a danger or damage the engine.

SAWING CONTRACTION JOINTS

As concrete hydrates or cures and begins to set, it develops internal stresses which may cause random cracks. Random cracks cast doubt on the quality and workmanship of the concrete. Contraction joints are cut in concrete to relieve these stresses before they seek their own relief in the form of random crack. The Soff-Cut Ultra Early Entry system controls random cracking through the early timing of a saw cut at predetermined locations to create weakened planes in the concrete that subsequently crack at the bottom of the cut to relieve stress. Husqvarna sawed contraction joints should be a minimum of 1/8th the concrete depth and a minimum of 1” (25mm) deep. Contraction joints should be sawn as soon as the concrete will support the weight of the saw and the operator without marking or damaging the concrete. There are many possibilities for joint layout. Joint layout should be provided, the saw contractor should submit a detailed joint layout for approval prior to cut- ting. Several factors affect joint spacing including:

• Concrete thickness
• Type, amount and location of reinforcement
• Shrinkage potential of concrete-cement (type, quantity), aggregate (size, quantity, quality), water to cement ratio, admixtures, concrete temperature
• Base friction
• Slab restraints
• Layout of foundations, racks, pits, equipment pad, trenches, etc.
• Environmental factors – temperature, wind, humidity
• Methods and quality of concrete curing.
• Generally, contraction joint patterns should divide slabs into approximate square panels per the recommended spacing shown.

RECOMMENDED CONTRACTION JOINT SPACING

At all intersecting cross cuts, install Husqvarna joint protectors at each joint to prevent joint damage. Install an additional joint protector where the right wheel will cross the joint to prevent concrete damage.

TROUBLESHOOTING
