must always be on the opposite side of the pivot point from where the load is being lifted
✔✔With a loaded fork lift, does your center of gravity change when you lift the load to a
higher point? - ✔✔Yes, the center of gravity shifts toward the pivot point as the load is
being lifted

✔✔Never okay to straddle
✔✔What does the term power cycle refer to when operating a backhoe front-end
loader? - ✔✔The RPM's are in the range where you get the most power out of the
engine, if the engine is rated for 2000 RPM's the power cycle would be between 1650-
1850 RPM's, below 1650 RPM's the engine is lugging, above 1850 RPM's the engine is
straining.
✔✔How would you gain traction with a backhoe/front end loader going up a steep hill? -
✔✔Ballast and use four wheel drive, or turn around and back down the hill
✔✔What is the roll over protection (R.O.P) law? - ✔✔All hoisting machinery must have
R.O.P and if damaged it must be replaced
✔✔What is clutch disconnect? - ✔✔It allows you to disconnect the transmission power
