general information The MQ Whiteman Power Buggy, Models WBH16 (recoil start) and WBH16E (electric start) are intended for the transportation of concrete, concrete spreading and spot pouring. In addition, the WBH16/WBH16E is designed for landscaping applications, material sub-base distribution, job site cleanup and material transport. The Power Buggy is equipped with a 6-inch dump height which provides clearance and enables the operator to maneuver over any form height.
components Figure 2. WBH16/WBH16E Power Buggy Components 1. Tub or Bucket — Used for the transportation of material. Tub holds approximately 16 cubic feet (0.59 cubic yards) of water. 10. Engine — The WBH16 uses a HONDA GX390K1QA2 (recoil start) engine. The WBH16E uses a HONDA GX390K1QAE2 (electric start) engine. 2. Handle Bar (Steering) — This handle bar is used to steer the buggy. When driving the buggy, use both hands and hold onto both handle bar grips. 11.

Replace hydraulic oil after every 200 hours of operation. The hydraulic oil filter should be changed each time the hydraulic oil is changed.
maintenance pump control lever adjustment Table 4. Tire Wear Troubleshooting If the power buggy tends to creep in the forward or reverse direction after you release the speed control lever, the pump control lever requires adjustment. 3. Place the machines drive wheels on jacks or blocks free from ground contact. 4. Locate the pump control lever adjusting bolt. 5. Loosen the jam nut. 6.
