This document is an owner's manual for Supaswift 20" Alloy Base Commercial Rotary Lawn Mowers, specifically models SSU797KMC and SSU797HMC. It provides comprehensive instructions for setting up, operating, and maintaining the mower, emphasizing safety, proper usage, and care to ensure longevity and optimal performance.

The primary function of these devices is to cut grass using a rotary blade system. As commercial models, they are designed for robust performance and durability, suitable for professional landscaping tasks. A key feature highlighted is the mulching capability, which allows the mower to finely chop grass clippings and redistribute them onto the lawn, acting as a natural fertilizer and reducing the need for bagging.

Important Technical Specifications (Inferred and Explicit):

• Type: 20" Alloy Base Commercial Rotary Lawn Mower.
• Models: SSU797KMC, SSU797HMC.
• Engine: 4-stroke engine (requires oil and unleaded fuel, shipped without oil in the sump). Specific engine details are referred to in a separate engine owner's manual.
• Cut Height Settings: Ten height settings, adjusted via a lever at the rear right-hand wheel.
• Blade Tightening Torque: Central bolt: 57-62Nm; three concentric bolts: 8-11Nm.
• Blade Retaining Nuts Torque: 16Nm.
• Self-Propelled Drive (if equipped): Features a clutch engagement lever for rear-wheel drive.
• Clutch Spring Length (Disengaged): 18mm.
• Clutch Spring Length (Engaged): Stretched to 28mm (10mm longer).

Usage Features:

• Safety First: The manual strongly emphasizes safety, including wearing appropriate footwear, clearing the mowing area of debris, disconnecting the spark plug before maintenance, and never operating the mower while tired or under the influence. It warns against operating in confined spaces due to exhaust fumes and advises against mowing on excessively steep slopes.
• Starting the Engine: Detailed instructions refer to the engine owner's manual for specific procedures but generally involve moving the throttle to "CHOKE" or "FAST" and priming the engine, then pulling the cord rapidly.
• Stopping the Engine: Move the throttle control lever to the "STOP" position and wait for the engine to come to a complete stop.
• Adjusting Cut Height: The mower offers ten height settings. To adjust, grasp the height adjustment lever, pull it away from the base to disengage, move it to the desired position, and release. Users are warned to stand clear of cutting blades during adjustment.
• Mulching Operation:
  • Installation of Mulch Plug: Involves raising the rear flap, removing the grass catcher (if fitted), inserting the mulch plug (right-hand side first), rotating the left-hand side, aligning locating pins with slots, and lowering the plug until it rests flat. The rear flap should close against the plug's vertical face.
  • Removal of Mulch Plug: With the engine stopped, raise the rear flap, grasp the rear of the plug, lift it up and away, then rotate and guide it out.
  • Mulching Tips: To optimize mulching, the manual advises keeping blades sharp, maintaining the sharpening angle, ensuring the cutting edge is feather-free, keeping the mower deck and mulch plug clean, avoiding mulching wet grass, not cutting too low (maximum 25mm or 1/3 blade height), not pushing the mower too fast, and running the engine at full throttle.
  • Benefits of Mulching: Includes quick breakdown of clippings for soil nutrients, reduced water evaporation, temperature control for grass roots, and assistance in controlling soil erosion. For the user, it eliminates raking leaves and cut grass, saves time emptying the catcher, and disposes of clippings automatically.
• Self-Propelled Drive (if equipped):
  • Engaging Drive: Start the engine, move the throttle to "FAST," then slowly push the clutch engagement lever to engage the self-propelled drive to the rear wheels.
  • Disengaging Drive: Release the clutch engagement lever and allow it to return to the disengaged position. A caution warns against holding the lever in a semi-engaged position to avoid excessive clutch wear.

Maintenance Features:

• General Cleaning: Recommended after every use to prevent corrosion, overheating, and fire risk.
  • Underside: Place the mower outdoors on a flat surface, set cut height to maximum, remove grass catcher/mulch plug, lift discharge flap, and use a garden hose to wash out clippings. Repeat if not clean. Caution: Do not hose the engine.
  • Upper Side: Use a dry cloth or soft brush for loose clippings, a damp cloth with mild detergent for oil/grime, and wash the grass catcher/mulch plug separately. Allow to dry before storing.
• Engine Maintenance: Refers to the engine owner's manual for detailed instructions.
  • Air Cleaner: Service every 25 hours, more regularly in dusty conditions, replace if damaged.
  • Spark Plug: Remove every 50 hours for gap checking, replace every 100 hours, or sooner if electrodes are pitted/burned or porcelain cracked.
• Muffler: Check periodically for rust/cracks and replace with genuine parts if damaged.
• Blades and Cutting Assembly:
  • Inspection: Check blades and central fasteners regularly, or after striking an object, or if the mower vibrates abnormally. Replace worn or damaged blades in sets to maintain balance.
  • Blade Change: With the engine stopped and spark plug lead removed, open the discharge flap, set the mower to high cut, fold the handle bar forward, and carefully rotate the cutting assembly. Use gloves and a spanner to remove the blade assembly. Retain "D" plates, discard old blades/fasteners. Fit new blades and fasten in the correct order, tightening to 16Nm.
• Self-Propelled Mowers Only:
  • Adjusting Drive Cable: Check that the drive disengages before starting the mower. Measure clutch spring length in disengaged (18mm) and engaged (28mm) positions. Adjust using the thumb wheel on the cable support block (anti-clockwise to increase stretch, clockwise to decrease).
  • Drive Wheel Cleaning and Pawl Lubrication (Every 50 hours): Disconnect spark plug, support rear wheels, remove wheel caps, nyloc nut, and tension washer. Remove wheel and clean hub. Remove circlip, outer washer, outer bush, pinion gear, and pawl (noting orientation). Clean all components, lightly grease the pawl, shaft slot, bushes, and pinion gear, then refit. Note: Pinion gear (H) is marked "R" and "L" for right and left side fitting, respectively. Replace wheel, tension washer, nyloc nut, and wheel caps.

Warranty Conditions:

• Manufacturer's Warranty: Covers defects in material and workmanship, limited to repair or replacement of defective parts.
• Engine Warranty: May differ from other components; refer to the engine owner's manual.
• Duration: 2 years for domestic use, 120 days for commercial use, and 90 days for hire.
• Exclusions: Transport costs, fair wear and tear (blades, blade bolts, V-belts, spark plugs), damage from misuse/abuse, use of non-genuine parts, or unauthorized repairs/alterations.
• Australian Consumer Law: States that the warranty benefits are in addition to other consumer rights and guarantees that cannot be excluded. Consumers are entitled to replacement or refund for major failures and compensation for foreseeable loss, or repair/replacement for non-major failures.
• Proof of Purchase: Recommended for warranty work. Repairs must be carried out by an authorized dealer/agent using genuine spare parts.

The manual concludes with a section for recording retailer information, address, phone number, model number, serial number, and date of purchase, and provides contact information for further assistance.
