Terramite T5C User Manual

Safety Tips

Safety is a prime consideration in the design of this machine. Guards, shields and other safety features are built in wherever possible. However, accident reports show carelessness causes the majority of accidents. You can avoid most accidents by observing the safety rules on these pages. Study these rules carefully and enforce them on the job:

Never allow minors to operate or be in the vicinity of the machine while working.

Do not allow the T5C to be operated by anyone who is intoxicated or on medication that would affect their judgement or ability to operate the machine.

The machine is designed to be operated by adults who are of average size and weight. Persons who are extremely heavy, big or tall, or those who are exceedingly short, light or weak can not run the machine.

Before Operating the Terramite T5C

Read the Operator's Handbook. Never allow anyone to operate the backhoe without reading the Operator's Manual and Safety Instructions. This should be followed by supervised training.

Check Your Equipment. Always make a complete inspection of the machine before operating it that day. Check the hydraulic system and the engine oil level. Then check the machine for broken, missing or defective parts. Check the tires for cuts, bulges, irregularities and abnormal wear and proper inflation. Check the neutral position of the foot pedal. A malfunctioning machine invites accidents.

"Do Not Operate" Tag. When you service the machine, put a "DO NOT OPERATE" Tag on the instrument panel. This tag (Terramite Part Number 1-400.82) is included with each machine.

Keep Your Machine Clean. Slippery surfaces are hazardous. Remove oil, grease or mud from the operating area of the tractor. Failure to keep these areas clean could cause a serious accident.

Wear What is Needed for Protection.

Protect yourself by wearing all the protective clothing and personal safety devices issued to you or required by job conditions. You may need a hard hat, safety shoes, safety glasses, heavy gloves, hearing protection, reflective clothing, wet weather gear and a respirator. Never take chances by wearing loose clothing, watches or rings.

Look For Hazards. Walk around a new work area and check for any hidden hazards, such as holes and abutments.

Read and Heed Safety Decals. Make sure the safety and information decals can be easily read. To clean decals, use soap and water only. Gasoline or solvents will destroy the decals. If these decals are missing or illegible, call our Parts/Service Department for replacements.

Roll-Over Protective Structure. All Terramite T5C tractor loader backhoes are equipped with a Roll-Over Protective Structure. This is designed to protect the operator in the event of a roll-over. If this machine has been rolled over, the R.O.P.S. must be replaced. It is designed to be used only once.

Driving Pivot Pins. When driving pivot pins in or out, use care to guard against injury from particles that may chip off the pin or object used in striking the pin. These pins can fly out at high speed if they are not tapped lightly just before they come out. Make sure there isn't anyone or anything in the way, in case the pin flies out. Safety glasses should be worn.

Oil Change and Type Specifications

When your machine is new, the hydraulic system oil and filter must be changed within the first 50

hours of use and every 250 thereafter. Refill the hydraulic reservoir with engine oil type API SF.CD 15W40 when outside temperature is above 40 degrees F. Use engine oil type API SF.CD 10 weight when outside temperature is below 40 degrees F. Replace filter with Terramite / 21002 filter. It is important to follow these instructions to alleviate any cold weather engine starting problems and any pressure or heat related component failures.

DO NOT USE REGULAR HYDRAULIC OIL!

MAJOR DAMAGE WILL RESULT!

This is the position machine must be in to check proper level in hydraulic tank.

Required Pre-Fuel Filter Changes for Gasoline and Diesel Machines

ALL Terramite Backhoes and Street Sweepers require their pre-fuel filters to be changed at the first 20 hours and again at 40 hours. These pre-fuel filters should be changed every 20 to 50 hours thereafter using a 10 micron filter.

The following Pre-fuel filters are designed for gasoline and diesel engines.

Terramite 15506

NOTE:NOTE:

NOTE: Filling tank with loader or backhoe in any other position will result in overfilling and spillage of fluid

NOTE:NOTE:

through the breather cap. Replace cap if oil should ever spill out of breather cap since it will clog off the air supply that the systems needs to operate properly.

Parts Ordering Information

As of April 1, 1991, the section seals for the V20 changed. The new versions have larger cross section (old was .070, new is .103) and different configurations for open center and closed center sections. The old design utilized the same seals for all versions (two .801 I.D. and two .926 I.D.). The new design uses one configuration for open center (three .924 I.D. and one .799 I.D.) and another configuration

PARTS MANUAL

for closed center, load sensing and all outlet covers (two .924 I.D. and two .799 I.D., with one .237 I.D. for load sensing).

The following charts is provided to aid in selection of the proper seals. It is important to note that the seal kits include all O-rings (new and Old), therefore there will be some left unused.

The following section seals are included in the Kits:
