Six models, one manual. This 131-page Kubota Brush Cutter Workshop Manual (OEM #9Y111-10500) documents the DM262-S, DM262-W, DH264-S, DH264-W, DM332-S, and DM332-W in full factory detail. It covers inspection and adjustment across the crankcase, crankshaft, piston rings, centrifugal clutch, carburetor, and recoil starter, backed by exploded views and torque tables for every fastener on the machine. The troubleshooting section walks through hard-start diagnosis and engine faults; the maintenance chapter lays out each 20-hour and 50-hour interval, from air filter cleaning to gear case lubrication. Looking for the cutting blade spec? Torque the saw lock nut to 14.7 to 19.6 N·m on the DM262 and DH264, or 24.5 to 29.4 N·m on the DM332. When the machine is down, this gets you to the right page in seconds instead of scrolling forum threads.

Kubota DM262-S & variants Common Problems This Manual Covers
Kubota DM262-S brush cutter pulls hard but refuses to fire or starts intermittently when cold
Inspect the ignition system and fuel delivery using the troubleshooting steps. Clean the fuel filter every 50 hours as shown on page 90. Set the spark plug electrode gap to 0.6 to 0.7 mm using a feeler gauge, and torque the plug to 12 N·m per page 104.
Manual Section: General Troubleshooting Symptoms and CausesTrimmer head stops spinning under heavy load in dense brush or tall wet grass p. 84
Measure the centrifugal clutch engagement on page 84 and confirm the clutch-IN speed reaches 3650 to 4050 rpm. A lining that is worn or peeling means the clutch assembly needs replacing; torque the M8 clutch bolt to 8 to 10 N·m as specified on page 85.
Manual Section: EngineExcessive vibration and rattling noise from the lower shaft gear case during high speed operation p. 26
Pull the gear case and inspect the bearings, exchanging any damaged by heat or where snap rings have loosened (page 26). Fit new, greased O-rings on reassembly following the precautions on page 15, then torque the M5 housing bolts evenly to 2.9 to 3.9 N·m per page 17.
Manual Section: MaintenanceEngine runs rough and stalls out completely when dropping back down to idle speed p. 22
Service the air filter before each session or every 20 hours (page 22): wash the element in white kerosene or gasoline, squeeze it hard, and soak it with lubricating oil per page 91. Dial the throttle wire free play to 0.5 to 1.0 mm as directed on page 25.
Manual Section: MaintenanceFrequently Asked Questions
What are the torque specs for the Kubota DM262-S / DM262-W / DH264-S / DH264-W / DM332-S / DM332-W?
Where a torque isn't called out specifically, use the general table: M4 at 2.0 to 2.9 N·m, M5 at 2.9 to 3.9 N·m, M6 at 4.4 to 9.8 N·m. The saw lock nut runs 14.7 to 19.6 N·m on the DM262-S/W and DH264-S/W, and 24.5 to 29.4 N·m on the DM332-S/W. Clutch bolts take 6 to 8 N·m (M6) or 8 to 10 N·m (M8), and the flywheel M8 nut takes 12 to 14 N·m.
How do I adjust the carburetor on a Kubota DM262 or DM332?
The carburetor is set at the factory, so adjustment usually isn't needed. If it is, set idle with the idle speed screw: right turns raise RPM, left turns lower it. On the TU33 and TU43, the idle needle can be reset by closing the screw fully and backing it out 360°, where clockwise leans the mixture and counter-clockwise richens it.
How do I replace the clutch on a Kubota DH264?
This manual's engine section (pages 27 to 131) documents the Mitsubishi Meiki TU series. The DH264 instead runs a Honda GX25 engine (page 8), and the GX25 clutch procedure isn't included here. For DH264 clutch service, you'll need a Honda GX25 service manual.
What are the replacement specifications for cutting blade / cutter assembly?
Never cut with a dull, cracked, or damaged metal blade. The Maintenance Check List says to replace the cutting tool once it's damaged. On rotary blades, the base of each tooth should be rounded (R 2 to 3 mm or R 3 to 4 mm, with L: 1 to 2 mm), shaped to match the figure shown.
What are the replacement specifications for drive belt / transmission wear parts?
There's no drive belt to replace: these brush cutters drive through an angle transmission with spiral bevel gears. For wear parts, swap out bearings and oil seals that are heat-damaged or where snap rings have loosened, and replenish the angle transmission lubrication every 20 hours.
Is this Kubota DM262-S & variants Workshop Manual a digital download?
