B-SERIES TROWEL — INSTRUCTIONS
The easiest way to make this adjustment is to use the Trowel Arm Adjustment Fixture, Part Number 1817 (pictured below). This fixture will allow consistent adjustment of the trowel arm fingers. It comes with all the hardware necessary to properly accomplish this maintenance and instructions on how to properly utilize this tool. Adjusting the trowel arm fingers without a fixture requires a special talent.
If a trowel arm adjustment fixture is not available and immediate adjustment is necessary , we suggest the following procedure. If you can see or feel which blade is pulling harder, adjust the bolt that corresponds to that blade. Another way to determine which blades need adjusting is to place the machine on a flat surface and pitch the blades as flat as possible. Now, look at the adjustment bolts. They should all barely make contact with the lower wear plate on the spider. If you can see that one os them is not making contact, some adjustment will be necessary.
It is possible to either adjust the “high” bolts down to the level of the one that is not touching, or adjust the “low” bolt up to the level of the higher ones.Verify that after adjustment, the blades will pitch correctly. Often times, if the blades are incorrectly adjusted, they will not be able to pitch flat. This is due to the adjusting bolts being raised too high. Conversely, some times the adjusting bolts are too low and the blades cannot be pitched enough.
Changing a Blade
It is recommended that all the blades be changed at the same time. The machine may wobble or bounce if only some of the blades are changed at one time.
1.Place the machine on a flat, level surface. Adjust the blade pitch control to make the blades as flat as possible. Note the blade orientation on the trowel arm.
2.Remove the bolts and lock washers on the trowel arm, then remove the blade.
3.Scrape all concrete particles from the trowel arm.
4.Install the new blade, maintaining the proper orientation for direction of rotation.
5.Affix the bolts and lock washers.
6.Repeat steps
Hand Clutch Adjustment
Some finishers are equipped with a
There are two reasons to adjust the hand clutch: 1) operator comfort; 2) initial belt stretch and
The easiest and most simple adjustment is to adjust the clutch cable housing using the adjusting nut located on the clutch lever. Rotating the nut provides either more or less (depending upon the direction of rotation) clutch engagement.
Always check to verify that the clutch will properly disengage!
For operator comfort: start the trowel following the instruction given earlier in this manual. Move the throttle lever so that the engine is running
about 1/4 to 1/3 of full speed. Grip the trowel handle firmly and carefully engage the clutch by squeezing the clutch lever toward the handle with your left hand. After the trowel is stabilized and you feel comfortable with its operation, use your right hand to adjust the housing adjustment nut. Rotating the nut so that it backs out of the lever housing increases the engagement and also the squeezing force required to keep it engaged.Too much squeezing force may cause premature hand fatigue. Too little squeezing force may cause belt slippage and premature belt wear. Each operator should experiment with the adjustment to get the optimum combination of squeeze force and belt grip.
After initial
After considerable belt wear, the adjustments mentioned above may have a little or no effect on clutch engagement. If this is the case, the belt should be replaced.
