Classen SA-25 manual User Clothing, Inspect Aerator Before Each Use, Scheduled Aerator Maintenance

User Clothing

DO NOT operate the aerator while wearing sandals, tennis shoes, or shorts. Always wear long non-baggy pants. Wear high-top leather work boots with thick, textured tread at all times. Hard or smooth soled shoes are too slippery for a good footing on aerator platform. NEVER wear loose fitting clothing which could get caught in the moving parts. Wearing safety glasses, ear protection and safety shoes is advisable.

Inspect Aerator Before Each Use

DO NOT use the aerator if any parts are not maintained in good operating condition. Examine the moving parts prior to each use. Look for excessive wear, bald or worn tires, cracks in parts, loose or missing bolts, cotter, lynch, or hair pins and replace before operating the aerator. Make sure all safety equipment provided with the aerator is in good operating order, including all the warning decals. Inspect the rear wheels and their respective bolts for tightness and proper operation. Ensure that all parts of the hand-operated transmission control system are tight and secure. This is to reduce the possibility that the aerator could have a loss of control or safety.

Scheduled Aerator Maintenance

Replace worn rear drive tires with less than 3/32” of any tread groove left. Grease all fittings (12 total) daily. Each grease fitting should be filled until full.

•4 fitting on the swing arm.

•1 fitting on each of the front wheels.

•1 fitting on the left and right control handles.

•1 fitting on each tine disc hub.

•1 fitting on each female rod end.

Check roller chains for wear. Apply a light coat of No. 30 oil or penetrating chain lubricant to keep the chains in proper running order.

Check roller chain(s) for tightness. Follow these steps:

Model SA-25

1.Disconnect spark plug.

2.Take off pulley guard(s).

3.Loosen nuts by turning counter clockwise

4.Retighten nut by turning clockwise against lock washer.

5.Replace pulley guard, nuts and lock washers and retighten nuts.

DO NOT change the engine governor settings or over-rev the engine contrary to engine manufacturer specifications. Keep the Classen aerator in good operating condition, and keep safety devices and shields in place and in working condition. Keep all nuts and bolts tight to be sure the equipment is in safe working condition. Replace worn tines. Make sure the engine is turned off when doing ANY maintenance on unit. The aerator should not be used after the tine strikes a foreign object, until conducting a thorough inspection and any damage is repaired. When changing tines, pull out and remove the 3/8” snap lock pin (located in the upper-center of the foot platform

mount), and raise platform. Once platform is raised and secured in the up position, you have access to the tines. When you are done maintaining the tines, lower the platform, and re-secure the 3/8” snap lock pin.

Work Area Conditions and Inspection

Prior to operating the unit carefully inspect all lawn/ground areas where you plan to use the aerator for hidden, hard-to-see objects or uneven ground that may be hidden in the grass. Clear the work area of moveable objects such as wire, rocks, sprinkler heads, glass, etc. that might damage the aerator or be thrown. Remove, if possible, or mark the location of all immovable objects or irregular areas and be sure not to hit them with any part of the aerator. Obstacles such as holes, abrupt changes in the ground contour, tree trunks, stumps or roots, stub pipes protruding from the ground, paving edges, etc. in the path of operation can abruptly turn or stop the aerator. This could throw you off the aerator or into and possibly over the control handle causing serious injury or death. The faster you are moving the more potential there is for injury. Aerate only in daylight or in good artificial light. Keep away from drop-offs, the edges of ponds, streams, pools, etc. especially at the bottom of slopes. Do not aerate when children or others are around. Never operate the aerator in an enclosed area without good, approved ventilation. Exhaust fumes are dangerous.

Initial Operating Safety Guidelines

•Read and understand the warning decals on the unit.

•Keep a firm hold on the stationary handle at all times.

•Keep both feet on foot platform at all times.

•Know the controls and how to stop quickly.

•Before attempting to start engine, follow all starting instructions.

•Look behind before backing up.

•Before leaving the operator’s position for any momentary reasons, make sure the tines are up. Keep others from coming near the aerator. Get back on the aerator as soon as possible.

•When transporting, driving onto transport vehicles, into buildings, across parking lots or otherwise not aerating, lift tines up.

•When driving the machine onto a trailer, or transport vehicle, always back the machine onto the unit, for fear of tipping backwards.

•Before performing any maintenance, or repair service always turn engine off.

•DO NOT allow inexperienced people to operate the aerator until they have read and understood these safety instructions. Operate the aerator at slower speeds while becoming familiar with it.

•Speeding is dangerous for even an experienced operator. Sudden stops from excessive speed may cause serious injury.
