The pulley engages using a clutch. See the Parts section of this manu- All Allen Engineering Walk-behinds are equipped with a safety shutdown switch. Operating time between fuel refills is approximately 2-1/2 to 3 hours with a rotor speeds of 110 to 135 RPM.
3. If lubrication oil does not seep out as the drain plug is being removed, fill with type Allen Oil Kit P/N 048386 gearbox lubricant oil until the oil filler hole overflows. V-Belt Check A worn or damaged V-belt can adversely affect the performance of the trowel.
Page 36
SECTION 2 2.3, continued Controls OPERATIONS 1. Fine Pitch Control Handle – To adjust the pitch of the blades, turn the handle either clock- wise or counter-clockwise to achieve the desired blade pitch. 2. Handlebar Adjuster – Change the angle/height of the handle bars by loosening bolts, adjust handlebars to desired location, tighten bolts firmly to hold handlebars in that position.
2.3, continued SECTION 2 Engine Controls OPERATIONS 1. Fuel Filler Cap – Remove this cap to add unleaded gasoline to the fuel tank. Make sure cap is tightened securely. DO NOT over fill. 2. Throttle Lever – Used to adjust engine RPM speed (lever advanced forward SLOW, lever back toward operator FAST).
SECTION 2 Operating Instructions OPERATIONS 2.3.1 Operating The Trowel The following steps are intended as a basic guide to machine operation, and are not to be considered a complete guide to concrete finishing. We suggest that all operators (experienced and novice) read “Slabs on Grade” published by the American Concrete Institute, Detroit, Michigan.
Page 39
SECTION 2 2.3, continued Operating Instructions OPERATIONS Push down on the handle to move the rotor assembly to the right. Pull up on the handle assembly to move the rotor assembly to the left. Pitch Adjustment Different pitch angles are needed as you work the different stages of the concrete. When changing or setting pitch (angle of trowel blades), slow the machine down, set the desired degree of pitch on the left side of the machine and then adjust the right side to match.
SECTION 3 Periodic Maintenance SERVICE Periodic Maintenance Schedule The table below list basic trowel and engine maintenance. Refer to OEM engine manufacturer's Operation Manual for additional information on engine maintenance. A copy of the engine operator's manual was supplied with the machine when it was shipped.
Replace fill plug after proper level has been achieved. Fill so that there is oil 1/2 way in the sight glass. Use Allen Oil only. Each Gearbox has a grease fitting on top cover that must be greased (2 SHOTS ONLY) every 300 operating hours.
SECTION 3 Lift Lever Adjustment SERVICE Lift Lever Adjustment Procedure Damage to and/or replacement of a trowel arm can change the adjustment of the lift lever. This can unbalance the trowel arms and cause the riding trowel to wobble during operation. To operate smoothly the lift lever on all trowel arms must be adjusted the same to ensure that the riding trowel is balanced correctly.
