Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of the battery in the table below and charge the battery for the recommended time interval to bring the charge up to a full charge of 12.6 volts or greater.
IMPORTANT: Make sure the negative battery cables are disconnected and the battery charger used for charging the battery has an output of 16 volts and 7 amps or less to avoid damaging the battery (see chart below for recommended charger settings).
Voltage | Percent | Maximum |
| Charging Interval | |
Reading | Charge | Charger Settings |
| ||
|
| ||||
12.6 or greater | 100% | 16 volts/7 amps | No Charging Required | ||
12.4 – 12.6 | 75 | – 100% | 16 volts/7 amps | 30 Minutes | |
12.2 – 12.4 | 50 | – 75% | 16 volts/7 amps | 1 | Hour |
12.0 – 12.2 | 25 | – 50% | 14.4 volts/4 amps | 2 | Hours |
11.7 – 12.0 | 0 – 25% | 14.4 volts/4 amps | 3 | Hours | |
11.7 or less | 0% | 14.4 volts/2 amps | 6 | Hours or More | |
5.1.10Check hydraulic oil level. Service Interval: 40 hr.
a)Stop engine and wait for all moving parts to stop.
b)Clean area around hydraulic reservoir cap and remove cap.
c)Check hydraulic reservoir and if necessary fill the reservoir to the appropriate level with Mobil 1
NOTE: The baffle is labeled “HOT” and “COLD”. The oil level varies with the temperature of the oil. The “HOT” level shows the level of oil when it is at 225°F (107°C). The “COLD” level shows the level of the oil when it is at 75°F (24°C). Fill to the appropriate level depending upon the temperature of the oil. For example: If the oil is about 150°F (65°C), fill halfway between the “HOT” and “COLD” levels. If the oil is at room temperature (about 75°F (24°C)), fill only to the “COLD” level.
5.1.11Change hydraulic system filter.
Service Interval: After First 250 hrs, then yearly thereafter.
Note: Use only Exmark P/N
a)Place unit on a level surface. Stop engine, wait for all moving parts to stop, and remove key.
b)Carefully clean area around filter. It is important that no dirt or contamination enters the hydraulic system.
c)Unscrew filter to remove and allow oil to drain from reservoir.
IMPORTANT: Before
d)Fill reservoir as stated in Section 5.1.10.
e)Loosen filter 1/2 turn and allow a small amount of oil to leak from the oil filter (this allows air to be purged from the oil filter and supply hose from the hydraulic reservoir). Turn filter clockwise until rubber seal contacts the filter adapter. Then tighten the filter an additional 2/3 to 3/4 turn.
