2  How weight distribution affects skid loader steering and stability.  The difference between Tipping Load and Rated Operating Capacity  Understand the hydrostatic transmission.  Understand why maintenance is important.  Identify controls and their functions  Identify loader’s safety functions  Explain Safe entry and exit

3  Understand the reason for different attachments.  Understand safe maneuvering, traveling, and working with attachment.

4  With no load in the bucket, about 70% of the machine’s weight is on the rear axels while 30% is on the front.  With most of the load on the rear axels, the machine easily pivots or turns on the rear wheels.  With a load in the bucket, this ratio reverses; most of the load is now on the front axels.  The front axels become a pivot point.

5  The rated operating capacity is no more than 50% of the tipping load should be declared as the rated operating capacity.  The tipping load for the Bobcat we will be using is 2600 pounds.  Take half of 2600 pounds and you get the Rated Operating Capacity of 1300 pounds.  These numbers are under normal operating conditions.

6  Some loader attachments can affect the Rated Operating Capacity.  Never use non-approved attachments.  Never modify the loader.

7  Hydrostatic transmission is based on the transferring of fluids  This means every action you make on the levers has a precise reaction.  The loader will react the moment you move the steering levers.

8  Never try starting the loader from outside the cab. Everything you need is in the cab and that’s where it should be started from.  The steering levers control forward and reverse travel and used also used to turn the loader.

9  The foot pedals control the lift arm and the bucket or attachment.  Pushing on the top of the pedal is referred to as toeing, pushing bottom is referred to as heeling.  Heel the left pedal to raise the lift arms and toe the pedal to lower the lift arms.  Toe the right pedal to tilt the bucket forward and heel the pedal to tilt rearward.

10  For safety reasons keep your feet on the pedals.  The parking brake is located between the two control pedals.  Never exit the machine without first lowering the lift arms and placing the attachment flat on the ground.

11  The seat is adjustable  The seat belt must be worn at all times  The seat bar must be positioned in the down position before operating. The machine will not run, without the bar down.  Lift arm support is another feature. All work can be done with arms down, but if you would need them up use the lift arm support.

12  Before starting the loader you must do the following:  Enter the cab properly and seat yourself  Adjust the seat for comfort  Adjust and fasten the seat belt so that the buckle is centered between the hips and belt fits snugly.  Make sure the parking brake is engaged  Lower the seat bar  Place feet on hydraulic pedals and keep them there. Make sure pedals are in neutral.

13  Set the throttle to half position and make sure the steering levers are in the neutral position.  Always look at the instrument panel before you begin operating  Check to make sure the hydraulics work before arriving at your job site.  Raise and tilt the lift arms and bucket to get the hydraulic fluid cycling.

14  When the steering levers are returned to neutral, the loader will stop.  When getting out of the machine move pedals until they lock.  NEVER under any circumstance leave the operator’s seat while the engine is running or while the lift arms are in the raised position.

15  Engine Oil  Engine cooling system  Hydraulic and hydrostatic fluid levels  Lift arm and cylinder pivot pins  Tire condition and pressure  Look for loose or broken parts  Fuel level  The loader’s safety features

16  When fueling, the engine must be OFF.  Never use the loader or any attachment as a work platform or a personnel carrier  NEVER permit riders!  Never start moving until you are sure that no one is in your path. Make sure you know where people are all around you.

17  Keep lift arms down when moving or turning.  The 2 reasons are: To maintain stability and to be able to see where you are going.  Travel up and down slopes with heavy end pointed uphill while keeping the lift arms down and the bucket tilted up.  Remember with no load the rear of the loader carries the weight, with load the front is the heaviest!

18  Travel slow and keep bucket close to ground, just high enough to clear the ground.  Go around objects rather than over them.  Keep away from drop offs! The edge could give away and you could fall to the bottom.

19  To load the bucket from a material pile, toe the lift pedal until the lift arms are all the way down.  Toe the tilt pedal to put the cutting edge of the bucket on the ground.  Never ram the bucket into the material pile, drive slowly into the material.  Remember you get the greatest amount of power at the wheels with only minimal movement of steering levers.

20  Once you are in the pile, heel the tilt pedal to raise the front of the bucket. Do not overload the bucket.  With the load in the bucket, and the bucket “up,” back away from the material.  To empty the bucket, raise the lift arms and toe the tilt pedal until the bucket is empty.  Never travel with a load obstructing your view.

21  When dumping into a truck or bin, drive forward slowly, raise the arms until the bucket is just over the truck or bin.  Be careful not to spill the load onto the cab.
