Operation - Hyundai HYCH7070 User Manual

5. OPERATION

5.1. Adding fuel & oil.
5.1.1. Fill the fuel tank as instructed in the separate engine manual packed with the
machine.
5.1.2. Fill the machine with oil as instructed in the separate engine manual supplied with the
machine.
5.2. Disengaging the belt drive.
5.2.1. For easy starting of the engine, disengage the belt drive by pushing the lever
at the back of the housing down.
5.3. Starting the engine.
5.3.1. Move the fuel valve lever to the ON position.
5.3.2. To start a cold engine, move the choke to the CLOSE position. To restart a
warm engine, leave the choke lever in the OPEN position.
5.3.3. Move the throttle lever to the halfway position.
5.3.4. Turn the engine switch to the ON position.
5.3.5. Operate the starter.
5.4. Recoil Starter
5.4.1. Pull the starter grip lightly until you feel resistance, then pull briskly, return
the starter grip gently.
5.4.2. If the choke lever has been moved to the CLOSE position to start the engine,
gradually move it to the open position as the engine warms up.
5.5. Operating the machine.
5.5.1. After engine warms up, pull throttle lever to accelerate engine speed.
5.5.2. As the engine is increased slowly to full speed, gradually and slowly pull the
belt tension lever as far as it will go to engage the belt drive. This has to be
done slowly to allow the cutting disk to pick up speed; otherwise the engine will
stall because there is high inertia in the cutting disk.
5.5.3. The wood chipper can process a wide variety of dry or green organic
materials such as branch, pruning, stalks, vines, leaves, roots, and vegetable
matter. The maximum capacity is approximately 50 to 70 mm diameter
branches, depending on the type and hardness of wood. Rotating the branch as
you feed it into the machine will improve performance.
5.5.4. Feed limbs or branches through butt end first, leaving the bushy head on.
This helps guide the limb down the feed hopper, and reduces spinning and
bouncing of small pieces back up the feed hopper. Some side branches may
require pre-cutting so that the branch will "self-feed" more efficiently.
5.5.5. It is always advisable to process freshly cut materials, as wooden branches
get very hard and springy when dried out and become more awkward to handle
by making the knives blunt more quickly.
Fill tank to no more than 12.5mm (1/2") below the bottom of the filler
neck to provide space for expansion.
IMPORTANT: Allow the engine to run with no load until warm (1~5
minutes) after each start-up to stabilise.
