Safety Information Warning Symbols SECTION 2 SAFETY INFORMATION OWNER’S RESPONSIBILITY The procedures listed in this manual may not include all ANSI, OSHA, or locally required safety procedures. It is the owner/operator’s responsibility and not Las- tec to ensure all operators are properly trained and informed of all safety protocols. Owner/Operators are responsible for following all safety procedures when operating and performing maintenance to the Articulator.
Safety is a primary concern in the design and manufacture of all Lastec products. Unfor- tunately, our extensive efforts to provide safe equipment can be negated by a single care- less act of an operator.
Safety Information Pre-operational Safety Rules The best safety device is an informed, careful operator. We ask you to be that kind of operator. Pre-operational Safety Rules Do not allow children on or near the deck. Do not operate the deck when children are present. Clear area of all personnel before operating the deck.

Initial Set-Up Assembly SECTION 3 INITIAL SET-UP Assembly The Articulator comes preset from the factory and ready to mow. Should adjustments be necessary due to shipment, follow the set-up procedures listed herein. Parking Brake Set the parking brake before performing any set-up, inspection, adjust- ments, or maintenance to your Articulator.
Initial Set-Up Operator Seat Pan before operating. The fuel tanks have a gauge that shows the approximate fuel level at all times. Do not attempt to fuel your Articulator until you read and understand the entire INITIAL SET-UP section of this manual. GAS ONLY: Use only unleaded gasoline fuel.
Initial Set-Up Engine Oil 2. Clean the entire engine area and mower deck area (under the operator seat pan) of all excess grease, oil, fuel, grass, or debris before operating your Articulator to prevent dam- age to the equipment, fire hazard, and projectile hazards. 3.
The hydraulic oil used in your Articulator is formu- lated to prolong the life of the hydrostatic pumps. CM0035-1 Lastec offers the following oil kits (system capacity is approximately 5 quarts). Kit size Part number...
Initial Set-Up Hydrostatic Pump Adjustment 4. Use the sight gauge on the side of the hydraulic tank to fill to the “Fill Line.” 5. Inspect the motors and pumps, the filter, tank, all hoses, clamps, and fittings, and the entire area under the hydraulic system for leaks. 6.
Initial Set-Up Towing (Hydrostatic Pump Release) 4. If either drive tire rotates, adjust the hydro- static pump link arm for that tire. See Figure 3-3. a. Loosen the jam nut from the hydro- static pump link arm. (The jam nut is located between the rod end and the link arm).
See the Parts Manual or contact your Lastec dealer for the proper belt lengths for your Articula- tor. 4. Check for belt wear and/or wear to the nylon tensioning rods (part number 049571) if slip- page is occurring.
If you are unable to install a new belt with the idler system at its mini- mum stroke, it is likely you are installing the wrong size belt. Contact your Lastec dealer for proper belt lengths for your Articulator. 4. Ensure that the idler tensioning urethane spring is properly installed and in good condi- tion.
If the belt you are checking is new, and the idler tensioner slides to its maximum stroke without adequately tightening the belt, it is likely you have installed the wrong size belt. See section 5 of this manual or contact your Lastec dealer for the proper belt lengths for your Articulator.
Initial Set-Up Weight Transfer Springs Ensure to replace all covers and hardware. 3.13 Weight Transfer Springs The weight transfer springs help to lighten the mower deck by transferring excess weight to the drive unit, allowing more agile floating of the mower deck and a higher quality cut.
5. Replace any damaged, dull, cracked, or missing blades before operating your Articulator. Lastec also offers low-lift blades and mulching blades for certain mowing applications. Contact your Articulator dealer for further information about optional blades available. 3.15 Operator Seat 1.
Initial Set-Up Mower Deck Height a. Arms should also “snap” back to neutral posi- tion, which is straight up and down and cen- tered with the neutral position lock (notch in the frame). 4. Ensure to return and lock both control arms into neu- tral position.

Initial Set-Up Mower Deck Height Calibration Ensure to set the parking brake before making any adjustments to your Articulator. When you receive your Articulator, you will need to calibrate the mower deck height. 1. Park your Articulator on a flat, level surface. 2.
Page 35
Initial Set-Up Mower Deck Height Calibration 7. Use the center turnbuckle on the deck lift assemblies to level the center deck front-to-back. See Figure 3-11. Tolerances for front-to-back is positive 1/8 inch in the rear -- the rear should never be lower than the front edge. Retighten the jam nuts on the turn- buckle after leveling the deck.
Initial Set-Up Tires and Wheels The factory setting is approximately 1 inch, and should be readjusted to meet your needs. Do not allow the anti-scalp roller to be on the ground constantly or it will result in premature wear. 3.19 Tires and Wheels 1.
Initial Set-Up Engine 3.21 Engine 1. Check the exhaust while the engine is running. During proper operation, the exhaust should be colorless. If the engine runs continuously with dark exhaust, stop the engine and correct the problem before operating your Articu- lator.
Operating Procedures Starting The Engine SECTION 4 OPERATING PROCEDURES Starting The Engine Do not allow extended running of any engine indoors. Do not attempt to operate your Articulator until you have read and understand this manual in its entirety. Do not allow anyone to operate your Articulator without proper training and without first reading and understanding this manual in its entirety.
Operating Procedures Stopping The Engine 3. Release the key (which will return to the running position) when engine starts. 4. Adjust the throttle lever (located to the lower right of the operator seat) forward (down- ward) until the engine is running at a steady idle. NOTE: Do not overpower the engine.
Operating Procedures Recommended Blades Release the parking brake. In order to maneuver your Articulator, you must first remove both steering control arms from the neutral lock position. Grasp each steering control arm with each hand, and pull them both toward the center of the unit until they are free from the neutral lock. To travel forward: Push both control levers forward evenly.
Operating Procedures Ground Speed LOW-LIFT BLADE Low-Lift Blade is recommended for 1”-2” cutting height. Use a Low Lift Blade when the conditions are dry, the region is experiencing a drought, in sandy soil areas or when per- forming seasonal scalping. When conditions like this are evident, lift created by the cutter blades can be reduced, decreasing the abrasion wear to the cutter blades and deck caused by sand.
Operating Procedures Mower Deck Operation Mower Deck Operation Stay well clear of blades during operation. Clear area of all personnel before engaging the blades. Verify that all safety covers are in place before operating your Articula- tor. Do not aim/point/etc. the discharge in the direction of bystanders, vehi- cles, or buildings.
